-Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
+
-Preamble
+Permission is hereby granted, free of charge, to any person obtaining a copy
-The GNU General Public License is a free, copyleft license for software and other kinds of works.
+of this software and associated documentation files (the "Software"), to deal
-The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.
+in the Software without restriction, including without limitation the rights
-When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
+to use, copy, modify, merge, publish, distribute, sublicense, and/or sell
-To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.
+copies of the Software, and to permit persons to whom the Software is
-For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
+furnished to do so, subject to the following conditions:
-Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
+
-For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.
+The above copyright notice and this permission notice shall be included in all
-Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
+copies or substantial portions of the Software.
-Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.

-   To "modify" a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a "modified version" of the earlier work or a work "based on" the earlier work.
+SOFTWARE.
   A "covered work" means either the unmodified Program or a work based on the Program.
   To "propagate" a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
   To "convey" a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
   An interactive user interface displays "Appropriate Legal Notices" to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
   1. Source Code.
   The "source code" for a work means the preferred form of the work for making modifications to it. "Object code" means any non-source form of a work.
   A "Standard Interface" means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
   The "System Libraries" of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A "Major Component", in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
   The "Corresponding Source" for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.
   The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
   The Corresponding Source for a work in source code form is that same work.
   2. Basic Permissions.
   All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
   You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
   Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
   No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
   When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
   4. Conveying Verbatim Copies.
   You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
   You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
   5. Conveying Modified Source Versions.
   You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
      a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
      b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to "keep intact all notices".
      c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
      d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
   A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
   6. Conveying Non-Source Forms.
   You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
      a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
      b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
      c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
      d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
      e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
   A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
   A "User Product" is either (1) a "consumer product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
   "Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
   If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
   The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
   Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
   7. Additional Terms.
   "Additional permissions" are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
   When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
   Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
      a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
      b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
      c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
      d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
      e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
      f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
   All other non-permissive additional terms are considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
   If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
   Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
   8. Termination.
   You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
   However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
   Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
   Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
   9. Acceptance Not Required for Having Copies.
   You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
   10. Automatic Licensing of Downstream Recipients.
   Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
   An "entity transaction" is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
   You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
   11. Patents.
   A "contributor" is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's "contributor version".
   A contributor's "essential patent claims" are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
   Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
   In the following three paragraphs, a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
   If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. "Knowingly relying" means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
   If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
   A patent license is "discriminatory" if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
   Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
   12. No Surrender of Others' Freedom.
   If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
   13. Use with the GNU Affero General Public License.
   Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
   14. Revised Versions of this License.
   The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
   Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.
   If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
   Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
   15. Disclaimer of Warranty.
   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
   16. Limitation of Liability.
   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
   17. Interpretation of Sections 15 and 16.
   If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee. END OF TERMS AND CONDITIONS
 How to Apply These Terms to Your New Programs
 If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
 To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
 <one line to give the program's name and a brief idea of what it does.>
 Copyright (C) <year> <name of author>
 This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
 This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
 You should have received a copy of the GNU General Public License along with this program. If not, see <http s ://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
 If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:
 <program> Copyright (C) <year> <name of author>
 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
 This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.
 The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an "about box".
 You should also get your employer (if you work as a programmer) or school, if any, to sign a "copyright disclaimer" for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see <http s ://www.gnu.org/licenses/>.
 The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read <http s ://www.gnu.org/philosophy/why-not-lgpl.html>.

-Once you've either cloned this git or downloaded the release file, simply copy
+<!-- tocstop -->
 the files within the archive to whatever location(s) that work for your setup.
 I've stored the files in this git archive in a directory structure that should
 match most default setups.  I suggest keeping the contents of the
 *'/root/scripts'* folder in that location since the root user must execute the
 script anyways.  If you edit the 503.html and mc_borg.details files in place,
 then you don't have to specify their locations when running the script.
-Remember to make the script executable!
+## quick start
-```Bash
+Clone this repo or download a release file into a directory of your choosing. For all examples in this document, I will assume you will run the script from */scripts/backup*. Make sure the script file is executable and you protect the *.details* file since it contains things like your repo password:
 ```bash
 # run commands as root
 sudo -s
 # find somewhere to clone the repo
 cd /usr/local/src
 # clone the repo from my server (best choice)
 git clone https://git.asifbacchus.app/asif/MailcowBackup.git
 # or clone from github
 git clone https://github.com/asifbacchus/MailcowBackup.git
 # make a home for your backup script
 mkdir -p /scripts/backup
 cd /scripts/backup
 # copy files from cloned repo to this new home
 cp /usr/local/src/MailcowBackup/backup/* ./
 # make script executable and protect your .details file
 chmod +x backup.sh
 chmod 600 backup.details
 ```
-In addition, you can rename this script file to anything you like.  The log file
+## configuration file
 will use that same name by default when naming itself and any mention of this
 file in the logs will automatically use whatever name you choose to give it.
-## Environment notes
+You will need to let the script know how to access your remote repo along with any passwords/keyfiles needed to encrypt data. This is all handled via the plain-text 'configuration details' file. By default, this file is named *backup.details*. The file itself is fully commented so setting it up should not be difficult. If you need more information, consult [page 4.0](https://git.asifbacchus.app/asif/MailcowBackup/wiki/4.0-Configuration-details-file) in the wiki.
-The script is designed to be easy to use but still be flexible enough to
+## running the script
 accommodate a wide range of Mailcow setups.  The script pulls nearly all it's
 configuration from the Mailcow configuration files themselves, so it adapts to
 nearly all customizations you may have in your environment.  The script accepts
 several optional parameters to override its default or detected settings.  In
 addition, it reads easy-to-edit external plain-text files for borg settings so
 you don't have to weed through the script code to supply things like passwords.
-**This script auto-detects the location of your Mailcow configuration file. If
+After setting up the *.details* file correctly and assuming you are running a default set up of mailcow according to the documentation, you just have to run the script and it will find everything on it's own. In particular, the defaults are set as follows:
 you have multiple files on your system with the same name as the configuration
 file, the script will likely get confused and exit with an error**
-## Why this script must be run as root
+- mailcow.conf is located at */opt/mailcow-dockerized/mailcow.conf*
 - docker-compose file is located at */opt/mailcow-dockerized/docker-compose.yml*
 - the log file will be saved in the same directory as the script with the same name as the script but with the extension *.log*
-This script must be run by the root user and will exit with an error if you try
+To get a list of all configuration options with defaults:
 running it otherwise.  This is because a default secured setup of borgbackup
 contains things like the repository private key that are locked out to root user
 access only.  In addition, the root user is guaranteed to have access to all
 files you might want to backup.
-## Script parameters
+```bash
-
+./backup.sh --help
 You can run the script with the *'-?'* parameter to access the built-in help
 which explains the parameters.  However, the following is a more detailed
 explanation of each parameter and how to use them. **Note that any parameters
 needing a directory (webroot, log file location, etc.) can be entered with or
 without the trailing '/' since it's stripped by the script anyways.**
 General usage:
 ```Bash
 /path/to/script/scriptname.sh -parameter argument -parameter argument ...
 ```
-### Optional parameters
+To run with defaults:
-#### Docker container STOP timeout before error: -1 _number_
+```bash
-
+./backup.sh
 The amount of time, in seconds, to wait for a docker container to STOP
 gracefully before aborting, logging the error and exiting the script.\
 **Default: _120_**
 #### Docker container START timeout before error: -2 _number_
 The amount of time, in seconds, to wait for a docker container to START
 before aborting, logging the error and exiting the script.\
 **Default: _180_**
 #### Path to 503 error page: -5 _/path/to/filename.html_
 The path to an html file for the script to copy to your webroot during the
 backup process.  This file can be scanned by your webserver and a 503 error can
 be issued to users letting them know that your Mailcow is 'temporarily
 unavailable' while being backed up.  A sample 503 page is included for you.
 If you remove the default file or the one you specify is missing, a warning will
 be issued by the script but, it will continue executing.  More details on the
 503 notification can be found later in the [503
 functionality](#503-functionality) section of this document.\
 **Default: _scriptpath/503.html_**
 #### Path to borg details file: -b _/path/to/filename.file_
 This is a text file that lays out various borg options such as repo name,
 password, additional files to include, exclusion patters, etc.  A sample file is
 included for your reference.  More details, including the *required order* of
 entries can be found later in this document in the [borg details
 file](#borg-details-file) section.\
 **Default: _scriptpath/mc_borg.details_**
 #### File name of docker-compose configuration file: -d _filename.file_
 This is the file name of your docker-compose configuration file that is used to
 build/start/stop containers.  This script will only search for this file within
 the same directory where your Mailcow configuration file is found.\
 **Default: _docker-compose.yml_**
 #### Log file location: -l _/path/to/filename.file_
 If you have a particular place and filename you'd like this script to use for
 it's log, then you can specify it using this parameter.  I would recommend
 *'/var/log/backup.log'*. By default, the script will name the log file
 *scriptname*.log and will save it in the same directory as the script itself.\
 **Default: _scriptpath/scriptname.log_**
 #### File name of Mailcow master configuration file: -m _filename.file_
 This is the file name of the Mailcow master configuration file that was
 generated after installation and contains all information needed to run Mailcow
 (database user name, volume directory prefixes, etc.)  This script will search
 your computer for either the default file name or the one you have provided.
 Upon finding it, the script will derive the file path and use that as the path
 in which to run all Mailcow/docker commands.  **Please do not have multiple
 files on your system with this name, the script WILL get confused and exit with
 an error.\
 **Default: _mailcow.conf_**
 #### Verbose output from borg: -v (no arguments)
 By default, the script will ask borg to generate summary only output and record
 that in the script's log file.  If you are running the backup for the first time
 or are troubleshooting, you may want a detailed output of all files and their
 changed/unchanged/excluded status from borg.  In that case, specify the -v
 switch. **Note: This will make your log file very large very quickly since EVERY
 file being backed up is written to the log.**
 #### Path to webroot: -w _/path/to/webroot/_
 This is the path to the directory your webserver is using as it's default root.
 In other words, this is the directory that contains the html files served when
 someone browses to your server.  The correct webroot depends greatly on your
 particular setup.
 If you directly connect to Mailcow via Docker, then your webroot is by default
 */opt/mailcow-dockerized/data/web*, unless you've made changes to your install
 locations.  If you are running behind a reverse-proxy, then your webroot is your
 webserver's webroot (*/var/www* or */usr/share/nginx/html*, for example).
 This is used exclusively for 503 functionality since the script has to know
 where to copy the 503 file.  If you don't want to use this functionality, you
 can omit this parameter and the script will issue a warning and move on.  More
 details can be found in the [503 functionality](#503-functionality) section
 later in this document.
 ## Borg details file
 This file contains all the data needed to access your borg remote data repo.
 Each line must contain specific information in a specific order or **needs to be
 blank if that data is not required**.  The sample file includes this data and
 example entries.  The file must have the following information in the following
 order:
    1. path to borg base directory **(required)**
    2. path to ssh private key for remote server **(required)**
    3. connection string to remote repo **(required)**
    4. password for borg repo/repo key **(required)**
    5. path to file listing additional files/directories to backup
    6. path to file containing borg-specific exclusion patterns
    7. prune timeframe options
    8. location of borg remote instance
 ### Protect your borg details file
 This file contains information on how to access and decrypt your borg repo,
 therefore, you **must** protect it.  You should lock it out for everyone but
 your root user. Putting it in your root folder is not enough!  Run the following
 commands to restrict access to the root user only (assuming filename is
 *mc_borg.details*):
 ```Bash
 chown root:root mc_borg.details   # make root the owner of this file
 chmod 600 mc_borg.details   # grant access to root user only (read/write)
 ```
-### borg specific entries (lines 1-4)
+To run with a custom log file name and location:
-If you need help with these options, then you should consult the borg
+```bash
-documentation or search my blog at
+./backup.sh --log /var/log/mailcow_backup.log
 [https://mytechiethoughts.com](https://mytechiethoughts.com) for borg.  Here's a
 very brief overview:
 #### Line 1: Path to borg base directory
 This is primary directory on your local system where your borg configuration is
 located, **NOT* the path to your borg binary.  The base directory contains the
 borg configuration, cache, security files and keys.
 #### Line 2: Path to SSH key for remote server
 This is the SSH key used to connect to your remote (backup) server where your
 borg repo is located.  **This is NOT your borg repo key!**
 > Please note:  If you are planning on executing this script via cron or some
 > other form of automation, it is *highly recommended* that you use an SSH key
 > **without** a password!  SSH is designed such that passwords cannot simply be
 > passed to it via environment variables, etc. so this is something not easily
 > automated by a script such as this for security reasons.  As such, your
 > computer will sit and wait for you to enter the password and will NOT execute
 > the actual backup portion of the script until the SSH key password is provided.
 > 
 > If you really want/need to use an SSH key password, you will have to look into
 > somethign like GNOME keyring or SSH-agent to provide a secure automated way to
 > provide that password to SSH and allow this script to continue.
 >
 > In practice, SSH keys without passwords are still quite safe since the key
 > must still be known in order to connect and most keys are quite long.  In
 > addition, they key only connects to the remote server, your actual information
 > within the borg repository is still encrypted and secured with both a key and
 > password.
 #### Line 3: Connection string to remote repo
 This is the full server and path required to connect to your borg repo on the
 remote server.  Very often it is the in the form of:
 ```
 user@servername.tld:repo-name/
 ```
-for rsync.net it is in the following form:
+To copy a 503 error page to your webroot:
-```
+```bash
-username@server-number.rsync.net:repo-name/
+# assuming default NGINX webroot (/usr/share/nginx/html)
 ./backup.sh -5
 # custom webroot
 ./backup.sh -5 -w /var/www/
 ```
-#### Line 4: Password for borg repo/repo key
+Common usage: custom log file and copy 503 to custom webroot
-This is the password needed to access and decrypt your *borg repo*.  Assuming
+```bash
-you set up your borg repo using recommended practices, this will actually be the
+./backup.sh -l /var/log/mailcow_backup.log -5 -w /var/www/
 password for your *borg repo private key*.  **This is NOT your SSH key
 password!**
 ### additional files/directories to backup
 This points to a plain-text file listing additional files and directories you'd
 like borg to include in the backup.  The sample file, *'xtraLocations.borg'*
 contains the most likely files you'd want to include assuming you're using a
 standard setup like I outline in my blog.
 The following would include all files in the home folder for users *'foo'* and
 *'bar'* and any conf files in *'/etc/someProgram'*:
 ```Bash
 /home/foo/
 /home/bar/
 /etc/someProgram/*.conf
 ```
-*You can leave this line blank* to tell borg to only backup your Mailcow data,
+Non-default mailcow location (example: */var/mailcow*):
 configuration and the SQL dump.  However, this is pretty unusual since you would
 not be including any server configuration files, reverse-proxy configurations,
 etc. If you omit this line, the script will log a warning to remind you of this
 unusual situation.
-### exclusion patterns
+```bash
-
+./backup.sh --docker-compose /var/mailcow/docker-compose.yml --mailcow-config /var/mailcow/mailcow.conf
 This points to a plain-text file containing borg-specific patterns describing
 what files you'd like borg to ignore during the backup.  To specify exclusions,
 create a text file in any location you want and specify exclusions patterns, one
 per line.  Then update line 6 in your borg details file with the path to your
 new exclusion file.
 You need to run *'borg help patterns'* for help on how to specify exclusion
 patterns since the format is not always standard BASH format and only sometimes
 uses standard regex.
 If you leave this line blank, the script will note it is not processing any
 exclusions and will proceed with backing up all files specified.
 ### prune timeframe options
 Here you can let borg prune know how you want to manage your backup history.
 Consult the borg documentation and then copy the relevant options directly into
 this line including any spaces, etc.  The example file contains the following as
 a staring point:
 ```Ini
 --keep-within=7d --keep-daily=30 --keep-weekly=12 --keep-monthly=-1
 ```
-This would tell borg prune to keep ALL backups made for any reason within the
+For more configuration options, see [page 3.0](https://git.asifbacchus.app/asif/MailcowBackup/wiki/3.0-Script-parameters) in the wiki and [page 4.4](https://git.asifbacchus.app/asif/MailcowBackup/wiki/4.4-Configuration-examples) for some configuration examples.

 last 7 days, keep 30 days worth of daily backups, 12 weeks of end-of-week
 backups and then an infinite amount of end-of-month backups.
-### borg remote location
+## scheduling your backup via cron
-If you're using rsync.net, then just have this say *'borg1'*.  If you are using
+Edit your root user's crontab and add an entry like this which would run the script using defaults at 1:07am daily:
 another provider, you'll have to reference their locally installed copy of borg
 relative to your home directory.  You can also leave this blank if your provider
 does not run borg locally but your backups/restores will be slower.

 ## 503 functionality
 This script includes an entire section dedicated to copying an html file to act
 as an error 503 notification page.  Error 503 is by definition "service
 temporarily unavailable" which is exactly the case for your Mailcow server
 during a backup since the mail-flow containers have been disabled.
 The script copies whatever file is defined by the *'-5'* parameter (or the
 default located at *'scriptpath/503.html'*) to whatever path is defined as the
 'webroot' by the *'-w'* parameter.  This means that if you omit the *'-w'*
 parameter, the script will necessarily skip this entire process and just issue a
 warning to let you know about it.
 ### Conditional forwarding by your webserver
 The script copying the file to the webroot is the easy part.  Your webserver has
 to look for the presence of that file and generate a 503 error in order for the
 magic to happen.  To do that, you have to include an instruction to that effect
 in your default server definition and/or your Mailcow virtual server definition
 file depending on your setup.
 #### NGINX
 You can copy the following code into the relevant server definition(s) on an
 NGINX server:
 ```Perl
 server {
    ...
    if (-f /usr/share/nginx/html/503.html) {
        return 503;
    }
 ...
    error_page 503 @backup
    location @backup {
        root /usr/share/nginx/html;
        rewrite ^(.*)$ /503.html break;
    }
 }
 ```
 This tells NGINX that if it finds the file *'503.html'* at the path
 *'/usr/share/nginx/html'* (webroot on reverse proxy) then return an error code
 503.  Upon encountering a 503 error, rewrite any url to *'domain.tld/503.html'*
 and thus, display the custom 503 error page.  On the other hand, if it can't
 find 503.html at the path specified (i.e. the script has deleted it because the
 backup is completed), then go about business as usual.
 #### Apache
 I don't use apache for anything, ever... so I'm not sure how exactly you'd do
 this but I think you'd have to use something like:
 ```Perl
 RewriteEngine On
 RewriteCond %{ENV:REDIRECT_STATUS} !=503
 RewriteCond "/var/www/503.html" -f
 RewriteRule ^ - [R=503,L]
 ...
 ErrorDocument 503 /503.html
 ...
 ```
 Let me know if that works and I'll update this document accordingly.  Like I
 said, I don't use Apache so I can't really test it very easily.
 #### Disabling 503 functionality altogether
 If you don't want to use the 503 functionality for whatever reason and don't
 want your log file junked up with warnings about it, then find the section of
 the script file that starts with *'--- Begin 503 section ---'* and either
 comment all the lines (put a *'#'* at the beginning of each line) or delete all
 the lines until you get to *'--- End 503 section ---'*.
 ## Scheduling: Cron
 After running this script at least once manually to test your settings, you
 should schedule it to run automatically so things stay backed up.  This is
 easiest with a simple cron job.
 1. Open root's crontab:
    ```Bash
    sudo crontab -e
    ```
 2. Add your script command line and set the time. I'm assuming your script is
   located at *'/root/scripts'*, all files are at their default locations and
   you want to run your backup at 1:07am daily.
    ```Bash
    7 1 * * * /root/scripts/backup.sh -l /var/log/backup.log -w /usr/share/nginx/html > /dev/null 2>&1
    ```
    The last part redirects all output to 'null' and forwards any errors to
    'null' also.  You don't need output because the script creates a wonderfully
    detailed log file that you can review :-)
 3. Save the file and exit.
 4. Confirm by listing the root user's crontab:
    ```Bash
    sudo crontab -l
    ```
 ## The log file
 The script creates a very detailed log file of all major operations along with
 any errors and warnings.  Everything is timestamped so you can see how long
 things take and when any errors took place.  The script includes debugging
 notes such as where temp files are located, where it's looking for data, whether
 it created/moved/copied files, etc.  All major operations are tagged *'-- [INFO]
 message here --'*.  Similarly, warnings are tagged *'-- [WARNING] message here
 (code: xxxx) --'* and errors are tagged *'-- [ERROR] message here (code: xxx)
 --'*.  Successful operations generate a *'-- [SUCCESS] message here --'* stamp.
 Sections of the script are all colour-coded to make viewing it easier.  This
 means you should use something like *'cat backup.log | more'* or *'tail -n
 numberOfLines backup.log'* to view the file since the ansi colour codes
 would make it difficult to read in nano or vi.
 This tagging makes it easy for you to set up a log screening program to make
 keeping an eye on your backup results easier.  If you plan on using Logwatch
 (highly recommended, great program!) then I've done the work for you...
 ### Using Logwatch
 Log-group, conf and service files are included so that you can easily setup
 Logwatch to monitor the script's log file and report at your desired detail
 level as follows:
    1. 0: Summary of total successes, warnings & errors only
    2. 1-4: Actual success, error & warning messages
    3. 5: Same as above, but includes info messages
    4. 6+: Dumps entire raw log file including debugging messages
 A detailed breakdown of the files and all options are included in a separate
 readme in the *'/etc/logwatch'* folder of this git archive.
 If you don't really care how it works, you can just copy the files from this
 archive to your *'/etc/logwatch'* directory.  The directory structure is correct
 for a default Logwatch install on Debian/Ubuntu.  You will have to update the
 log-group file to reflect the path to your script's log file.
 ### Remember to rotate your logs
 The log file generated by this script is fairly detailed so it can grow quite
 large over time.  This is especially true if you are using verbose output from
 borg for any troubleshooting or for compliance/auditing.  I've included a sample
 commented *logrotate config file* in this git archive at *'/etc/logrotate.d'*
 which you can modify and drop into that same directory on your Debian/Ubuntu
 system.  If you are using another log rotating solution, then please remember to
 configure it so that your log files don't get overwhelmingly large should you
 need to parse them if something goes wrong with your backups.
 ## Final notes
 I think that's everything. If I've forgotten to document something, please let
 me know. I know this readme is long but, I hate how much stuff for linux and
 open-source programs/scripts in general are so poorly documented especially for
 newbies and I didn't want to make that same mistake.
 I don't script too often and I'm a horrible programmer, so if you see anything
 that can be/should be improved, please let me know or submit your changes!  I
 love learning new ways of doing things and getting feedback, so suggestions and
 comments are more than welcome.

-## LogFile Group file (/etc/logwatch/conf/logfiles/backup.conf)
+I hope this helps you get your mailcow backup integrated with logwatch easily and quickly. If you have any suggestions/improvements, drop me a line in the issues section!
 ### Log file location
 Update this as needed to point to the location and name of the log file
 generated by the backup script.  Remember, by default, the log file is created
 in the same directory as the script itself.
 ```Ini
 LogFile = /path/to/your/backup.log
 ...
 ```
 Best practices suggest you use the backup script's *-l* flag to change this
 location to something like */var/log/backup.log*, for example.  In that case,
 the entry would look like:
 ```Ini
 LogFile = /var/log/backup.log
 ...
 ```
 ### Archive location and name format
 If you want Logwatch to process old (archived) log files generated by something
 like *Logrotate*, then you have to specify the location and file name format of
 those files.  I've included the generalized compressed format of such rotated
 files as the default in the script.  Suppose you store your log files in the
 recommended location (*/var/log/*) and are using *Logrotate* with compression
 enabled, the archive line would look like:
 ```Ini
 ...
 Archive = /var/log/backup.log.?.gz
 ...
 ```
 This would tell Logwatch, when the archive option is set to true, that your
 *backup.log* files are archived as: *backup.log.1.gz*, *backup.log.2.gz*, etc.
 and are all located in */var/log/*.
 **Note: This line is totally optional and only used if you set the archive
 option in Logwatch to true (default).  You can comment/delete this line if you
 wish.**
 ### External script for timestamp processing
 Since the log file uses a non-standard (according to Logwatch) method of
 datestamping, a custom filter had to be created.  See the
 [relevant](#timestamp-processing-script-etclogwatchscriptssharedsqfullstampanywhere)
 section of this document for more information.
 The script file is called with an *\** before the filename.
 ```Ini
 ...
 *sqFullStampAnywhere
 ...
 ```
 If you change the name of this file, you will have to change this line.
 Remember that whatever you type here as a name is converted to all-lowercase
 so your filename should be all lowercase also.
 ## Service definition file (/etc/logwatch/conf/services/backup.conf)
 ### LogFile Group file definition
 The service file needs to know what group of log files it is responsible for
 processing.  This MUST match the name of your *LogFile Group file*:
 ```Ini
 LogFile = backup
 ...
 ```
 If you change your LogFile Group filename, then update it here too without the
 *.conf* extension.
 ### Report title
 The Logwatch output file (html or text) is divided into sections.  You can
 define the title to be anything that has meaning for you.  I have arbitrarily
 chosen *"System and Mailcow Backup"* but you can change it to anything you want by
 modifying the line:
 ```Ini
 ...
 Title = "System and Mailcow Backup"
 ```
 ### Detail level
 If you want to set the *detail* level of this service differently from your
 other services (which will use the *--detail* switch value or the value in your
 *logwatch.conf*), then you can define that level here.  By default, it appears
 like this in the service configuration file:
 ```Ini
 ...
 # Override the detail level for this service
 # Remember the levels are: 0, 1-4, 5, 6+
 # Detail = 0
 ```
 Simply change it to the value you want enforced.  For example, here I'm setting
 it to output level 5 regardless of whatever settings everything else is using.
 ```Ini
 # Override the detail level for this service
 # Remember the levels are: 0, 1-4, 5, 6+
 Detail = 5
 ```
 ## Service script (/etc/logwatch/scripts/services/backup)
 Logwatch calls any script with a name that **matches the service name**.  You'll
 notice that I just named everything *backup* to keep things simple.  You can
 change this to whatever you want, however.  If you changed the service name to
 *"MailcowBackup*.conf", for example, you would have to rename this script file
 to "*MailcowBackup*" with no extension.\
 *Note: The script is a PERL file (note the shebang) but it can be written in any
 language.*
 **In essence, Logwatch just spits out the log file(s) defined in the LogFile
 Group file as standard input (STDIN) for the script and then takes whatever is
 output (STDOUT) from the script to assemble into it's report.**
 ### Detail levels
 The script supports four (4) detail levels as follows:
 - **Level 0: Summary output only**
  - This will display an aggregate total of certain logged elements.  It will
    display the total number of overall successful script executions, total
    generated warnings and total errors encountered that stopped the normal
    execution of the script.  All totals are relative to the reporting period
    Logwatch is using (--range parameter).
    **This is the recommended reporting level.**  It does not take up much space
    and is quick to read.  If you notice warnings and/or errors, you should
    consult the full log.
 - **Levels 1-4 (all the same): Critical messages**
  - This uses the data which is summarized by Level 0 but outputs the actual
    messages in the log file.  For example, you will see the actual text of the
    errors logged instead of just a total number of errors.  This level of
    reporting is useful when *initially* monitoring the script's operation since
    you can see the actual text of any generated warnings/errors.
 - **Level 5: Verbose (debugging) output**
  - Like the previous level, this outputs the actual messages found in the log
    file.  However, it also includes *[INFO] tags* which contain logged
    operational messages such as created temporary directories,
    starting/stopping docker containers, whether the 503 page was copied, etc.
    This level of reporting is useful in diagnosing why errors are occurring or
    if you just want more insight into how the script works.
    **This level of output will make your Logwatch reports longer and consume
    more of your time to review. You should not use this level day-to-day.**
 - **Levels 6+ (all the same): Complete log file dump**
  - Any number greater than 5 passed as a detail level will trigger the script
    to dump the entire log file out to Logwatch line-by-line.  This is useful
    only if you are debugging an issue and cannot get access to the actual raw
    log file itself.  The actual log file is colour-coded which makes it much
    easier to read for debugging purposes.
    **Use this detail level only when you need to see the entire log file and
    cannot otherwise access the log file.**
 ## Timestamp processing script (/etc/logwatch/scripts/shared/sqfullstampanywhere)
 This is basically a modified version of the '*applyeurodate*' script that comes
 with Logwatch.  It had to be modified to search within [square brackets] and to
 accept characters coming before the stamp (i.e. ANSI colour codes).  If you
 change the '**stamp**' variable in the backup script to update the timestamp to
 your liking (which to totally fine!) then you'll probably have to update this
 file.  There are two lines you need to modify to suit your new '**stamp**'
 variable.
 ### The time format specification
 '*$SearchDate*' is the variable used in the PERL script to do exactly what it
 says, search for the date stamp.  I have it set up to look for the format
 '*year-month-date hour:minute:second*'.  Note, we don't care about brackets or
 anything here, we're just defining the format of the date/time stamp.
 ```Perl
 ...
 $SearchDate = TimeFilter('%Y-%m-%d %H:%M:%S');
 ...
 ```
 If you changed the '**stamp**' variable so it was formatted as '*month/day/year
 hour:minute*' (ex: '*[09/27/2018 18:38]*') then you'd update the **$SearchDate**
 variable as follows (note: no mention of the square brackets!):
 ```Perl
 ...
 $SearchDate = TimeFilter('%m/%d/%Y %H:%M');
 ...
 ```
 ### The search REGEX
 The PERL script uses a '*regular expression*' (REGEX) to search within the log file for
 '*$SearchDate*'.  For the default datestamp, this specification looks like:
 ```Perl
 ...
 if ($ThisLine =~ m/\[$SearchDate\] /o) {
 ...
 ```
 The REGEX appears between '*m/*' and '*/o*'.  In this case, it searches for
 '*$SearchDate*' inside [square brackets] appearing anywhere on the line.  This
 is because ANSI colour-codes often appear before the datestamp in the default
 log file.  If you have modified this so that your datestamp appears at the
 beginning of the line and in the example format in the section above (using
 slashes instead of dashes) then you'd rewrite this REGEX as follows:
 ```Perl
 ...
 if ($ThisLine =~ m/^\[$SearchDate\] /o) {
 ...
 ```
 or using regular brackets anywhere on the line:
 ```Perl
 ...
 if ($ThisLine =~ m/\($SearchDate\) /o) {
 ...
 ```
 or without any brackets but appearing at the beginning of the line:
 ```Perl
 ...
 if ($ThisLine =~ m/^$SearchDate /o) {
 ...
 ```
 ## Testing
 Run *logwatch --help* and note the options.  You can test just this service
 locally on your screen with the following command (assuming you kept default
 names for everything):
 ```Bash
 # Summary output, entire duration of log file
 logwatch --service backup --output stdout --format text --range all --detail 0
 # Minimal detail, yesterday only
 logwatch --service backup --output stdout --format text --range yesterday --detail 3
 # Verbose output, today only
 logwatch --service backup --output stdout --format text --range today --detail 5
 ```
 ## Final thoughts
 That's it!  I'm a horrible PERL programmer so if anyone can optimize/improve the
 script file used for Logwatch then please do it!  Otherwise, I hope this made
 sense and helped you integrate the backup script with Logwatch for easy
 monitoring :-)
