 ### Discussing How To Use LAMMPS
 
 The LAMMPS mailing list is hosted at SourceForge. The mailing list began in 2005, and now includes tens of thousands of messages in thousands of threads. LAMMPS developers try to respond to posted questions in a timely manner, but there are no guarantees. Please consider that people live in different timezone and may not have time to answer e-mails outside of their work hours.
-You can post to list by sending your email to lammps-users at lists.sourceforge.net (no subscription required), but before posting, please read the [mailing list guidelines](http://lammps.sandia.gov/guidelines.html) to maximize your chances to receive a helpful response.

 Anyone can browse/search previous questions/answers in the archives. You do not have to subscribe to the list to post questions, receive answers (to your questions), or browse/search the archives. You **do** need to subscribe to the list if you want emails for **all** the posts (as individual messages or in digest form), or to answer questions yourself. Feel free to sign up and help us out! Answering questions from fellow LAMMPS users is a great way to pay back the community for providing you a useful tool for free, and to pass on the advice you have received yourself to others. It improves your karma and helps you understand your own research better.

 ### Reporting Bugs
 
-While developers writing code for LAMMPS are careful to test their code, LAMMPS is such a large and complex software, that it is impossible to test for all combinations of features under all normal and not so normal circumstances. Thus bugs do happen, and if you suspect, that you have encountered one, please try to document it and report it as an [Issue](https://github.com/lammps/lammps/issues) on the LAMMPS GitHub project web page. However, before reporting a bug, you need to check whether this is something that may have already been corrected. The [Latest Features and Bug Fixes in LAMMPS](http://lammps.sandia.gov/bug.html) web page lists all significant changes to LAMMPS over the years. It also tells you what the current latest development version of LAMMPS is, and you should test whether your issue still applies to that version.

That text field with contain a template with several headlines and some descriptions. Keep the headlines that are relevant to your reported potential bug and replace the descriptions with the information as suggested by the descriptions.
 You can also attach small text files (please add the file name extension `.txt` or it will be rejected), images, or small compressed text files (using gzip, do not use RAR or 7-ZIP or similar tools that are uncommon outside of Windows machines). In many cases, bugs are best illustrated by providing a small input deck (do **not** attach your entire production input, but remove everything that is not required to reproduce the issue, and scale down your system size, that the resulting calculation runs fast and can be run on small desktop quickly).

 We encourage users to submit new features or modifications for LAMMPS to the core developers so they can be added to the LAMMPS distribution. The preferred way to manage and coordinate this is by submitting a pull request at the LAMMPS project on GitHub. For any larger modifications or programming project, you are encouraged to contact the LAMMPS developers ahead of time, in order to discuss implementation strategies and coding guidelines, that will make it easier to integrate your contribution and result in less work for everybody involved. You are also encouraged to search through the list of open issues on GitHub and submit a new issue for a planned feature, so you would not duplicate the work of others (and possibly get scooped by them) or have your work duplicated by others.
 
-How quickly your contribution will be integrated depends largely on how much effort it will cause to integrate and test it, how much it requires changes to the core code base, and of how much interest it is to the larger LAMMPS community. Please see below for a checklist of typical requirements. Once you have prepared everything, see [this tutorial](http://lammps.sandia.gov/doc/tutorial_github.html)

  for instructions on how to submit your changes or new files through a GitHub pull request
 
 Here is a checklist of steps you need to follow to submit a single file or user package for our consideration. Following these steps will save both you and us time. See existing files in packages in the source directory for examples. If you are uncertain, please ask on the lammps-users mailing list.
 
 * All source files you provide must compile with the most current version of LAMMPS with multiple configurations. In particular you need to test compiling LAMMPS from scratch with `-DLAMMPS_BIGBIG` set in addition to the default `-DLAMMPS_SMALLBIG` setting. Your code will need to work correctly in serial and in parallel using MPI.
-* For consistency with the rest of LAMMPS and especially, if you want your contribution(s) to be added to main LAMMPS code or one of its standard packages, it needs to be written in a style compatible with other LAMMPS source files. This means: 2-character indentation per level, no tabs, no lines over 80 characters. I/O is done via the C-style stdio library, class header files should not import any system headers outside <stdio.h>, STL containers should be avoided in headers, and forward declarations used where possible or needed. All added code should be placed into the LAMMPS_NS namespace or a sub-namespace; global or static variables should be avoided, as they conflict with the modular nature of LAMMPS and the C++ class structure. Header files must not import namespaces with using. This all is so the developers can more easily understand, integrate, and maintain your contribution and reduce conflicts with other parts of LAMMPS. This basically means that the code accesses data structures, performs its operations, and is formatted similar to other LAMMPS source files, including the use of the error class for error and warning messages.

All added code should be placed into the LAMMPS_NS namespace or a sub-namespace; global or static variables should be avoided, as they conflict with the modular nature of LAMMPS and the C++ class structure. There MUST NOT be any "using namespace XXX;" statements in headers. In the implementation file (<name>.cpp) system includes should be placed in angular brackets (<>) and for c-library functions the C++ style header files should be included (<cstdio> instead of <stdio.h>, or <cstring> instead of <string.h>). This all is so the developers can more easily understand, integrate, and maintain your contribution and reduce conflicts with other parts of LAMMPS. This basically means that the code accesses data structures, performs its operations, and is formatted similar to other LAMMPS source files, including the use of the error class for error and warning messages.
 * If you want your contribution to be added as a user-contributed feature, and it is a single file (actually a `<name>.cpp` and `<name>.h` file) it can be rapidly added to the USER-MISC directory. Include the one-line entry to add to the USER-MISC/README file in that directory, along with the 2 source files. You can do this multiple times if you wish to contribute several individual features.
 * If you want your contribution to be added as a user-contribution and it is several related features, it is probably best to make it a user package directory with a name like USER-FOO. In addition to your new files, the directory should contain a README text file. The README should contain your name and contact information and a brief description of what your new package does. If your files depend on other LAMMPS style files also being installed (e.g. because your file is a derived class from the other LAMMPS class), then an Install.sh file is also needed to check for those dependencies. See other README and Install.sh files in other USER directories as examples. Send us a tarball of this USER-FOO directory.
 * Your new source files need to have the LAMMPS copyright, GPL notice, and your name and email address at the top, like other user-contributed LAMMPS source files. They need to create a class that is inside the LAMMPS namespace. If the file is for one of the USER packages, including USER-MISC, then we are not as picky about the coding style (see above). I.e. the files do not need to be in the same stylistic format and syntax as other LAMMPS files, though that would be nice for developers as well as users who try to read your code.

+For submitting pull requests, there is a [detailed tutorial](https://lammps.sandia.gov/doc/Howto_github.html) in the LAMMPS manual. Thus only a brief breakdown of the steps is presented here. Please note, that the LAMMPS developers are still reviewing and trying to improve the process. If you are unsure about something, do not hesitate to post a question on the lammps-users mailing list or contact one fo the core LAMMPS developers.
 Immediately after the submission, the LAMMPS continuing integration server at ci.lammps.org will download your submitted branch and perform a simple compilation test, i.e. will test whether your submitted code can be compiled under various conditions. It will also do a check on whether your included documentation translates cleanly. Whether these tests are successful or fail will be recorded. If a test fails, please inspect the corresponding output on the CI server and take the necessary steps, if needed, so that the code can compile cleanly again. The test will be re-run each the pull request is updated with a push to the remote branch on GitHub.
-Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission. If you are not yet registered as a LAMMPS collaborator, you will receive an invitation for that.
-You may also receive comments and suggestions on the overall submission or specific details. If permitted, additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
+Next a LAMMPS core developer will self-assign and do an overall technical assessment of the submission. If you are not yet registered as a LAMMPS collaborator, you will receive an invitation for that. As part of the assesment, the pull request will be categorized with labels. There are two special labels: `needs_work` (indicates that work from the submitter of the pull request is needed) and `work_in_progress` (indicates, that the assigned LAMMPS developer will make changes, if not done by the contributor who made the submit). 
+You may also receive comments and suggestions on the overall submission or specific details and on occasion specific requests for changes as part of the review. If permitted, also additional changes may be pushed into your pull request branch or a pull request may be filed in your LAMMPS fork on GitHub to include those changes.
 The LAMMPS developer may then decide to assign the pull request to another developer (e.g. when that developer is more knowledgeable about the submitted feature or enhancement or has written the modified code). It may also happen, that additional developers are requested to provide a review and approve the changes. For submissions, that may change the general behavior of LAMMPS, or where a possibility of unwanted side effects exists, additional tests may be requested by the assigned developer.
-If the assigned developer is satisfied and considers the submission ready for inclusion into LAMMPS, the pull request will be assigned to the LAMMPS lead developer, Steve Plimpton (@sjplimp), who will then have the final decision on whether the submission will be included, additional changes are required or it will be ultimately rejected. After the pull request is merged, you may delete the pull request branch in your personal LAMMPS fork.
-Since the learning curve for git is quite steep for efficiently managing remote repositories, local and remote branches, pull requests and more, do not hesitate to ask questions, if you are not sure about how to do certain steps that are asked of you. Even if the changes asked of you do not make sense to you, they may be important for the LAMMPS developers. Please also note, that these all are guidelines and not set in stone.
+If the assigned developer is satisfied and considers the submission ready for inclusion into LAMMPS, the pull request will receive approvals and be merged into the master branch by one of the core LAMMPS developers.

+# Outline of the GitHub Development Workflow
+
+This purpose of this document is to provide a point of reference for the
+core LAMMPS developers and other LAMMPS contributors to understand the
+choices the LAMMPS developers have agreed on. Git and GitHub provide the
+tools, but do not set policies, so it is up to the developers to come to
+an agreement as to how to define and interpret policies. This document
+is likely to change as our experiences and needs change and we try to
+adapt accordingly. Last change 2018-12-19.

+
+## GitHub Merge Management
+
+In the interest of consistency, ONLY ONE of the core LAMMPS developers
+should doing the merging itself.  This is currently
+[@akohlmey](https://github.com/akohlmey) (Axel Kohlmeyer).
+If this assignment needs to be changed, it shall be done right after a
+stable release.  If the currently assigned developer cannot merge outstanding pull 
+requests in a timely manner, or in other extenuating circumstances, 
+other core LAMMPS developers with merge rights can merge pull requests,
+when necessary. 
+
+## Pull Requests
+
+ALL changes to the LAMMPS code and documentation, however trivial, MUST
+be submitted as a pull request to GitHub. All changes to the "master"
+branch must be made exclusively through merging pull requests. The
+"unstable" and "stable" branches, respectively are only to be updated
+upon patch or stable releases with fast-forward merges based on the
+associated tags. Pull requests may also be submitted to (long-running)
+feature branches created by LAMMPS developers inside the LAMMPS project,
+if needed. Those are not subject to the merge and review restrictions
+discussed in this document, though, but get managed as needed on a
+case-by-case basis.
+
+### Pull Request Assignments
+
+Pull requests can be "chaperoned" by one of the LAMMPS core developers.
+This is indicated by who the pull request is assigned to. LAMMPS core
+developers can self-assign or they can decide to assign a pull request
+to a different LAMMPS developer. Being assigned to a pull request means,
+that this pull request may need some work and the assignee is tasked to
+determine whether this might be needed or not, and may either implement
+the required changes or ask the submitter of the pull request to implement
+them.  Even though, all LAMMPS developers may have write access to pull
+requests (if enabled by the submitter, which is the default), only the
+submitter or the assignee of a pull request may do so.  During this
+period the `work_in_progress` label shall be applied to the pull
+request.  The assignee gets to decide what happens to the pull request
+next, e.g. whether it should be assigned to a different developer for
+additional checks and changes, or is recommended to be merged.  Removing
+the `work_in_progress` label and assigning the pull request to the
+developer tasked with merging signals that a pull request is ready to be
+merged.
+
+### Pull Request Reviews
+
+People can be assigned to review a pull request in two ways:
+
+  * They can be assigned manually to review a pull request
+    by the submitter or a LAMMPS developer
+  * They can be automatically assigned, because a developers matches
+    a file pattern in the `.github/CODEOWNERS` file, which associates
+    developers with the code they contributed and maintain.
+
+Reviewers are requested to state their appraisal of the proposed changes
+and either approve or request changes. People may unassign themselves
+from review, if they feel not competent about the changes proposed. At
+least two approvals from LAMMPS developers with write access are required
+before merging in addition to the automated compilation tests.
+Merging counts as implicit approval, so does submission of a pull request
+(by a LAMMPS developer). So the person doing the merge may not also submit
+an approving review. The feature, that reviews from code owners are "hard"
+reviews (i.e. they must all be approved before merging is allowed), is
+currently disabled and it is in the discretion of the merge maintainer to
+assess when a sufficient degree of approval, especially from external
+contributors, has been reached in these cases.  Reviews may be
+(automatically) dismissed, when the reviewed code has been changed,
+and then approval is required a second time.
+
+### Pull Request Discussions
+
+All discussions about a pull request should be kept as much as possible
+on the pull request discussion page on GitHub, so that other developers
+can later review the entire discussion after the fact and understand the
+rationale behind choices made.  Exceptions to this policy are technical
+discussions, that are centered on tools or policies themselves
+(git, github, c++) rather than on the content of the pull request.
+
+### Checklist for Pull Requests
+
+Here are some items to check:
+  * source and text files should not have CR/LF line endings (use dos2unix to remove)
+  * every new command or style should have documentation. The names of
+  source files (c++ and manual) should follow the name of the style.
+  (example: `src/fix_nve.cpp`, `src/fix_nve.h` for `fix nve` command,
+  implementing the class `FixNVE`, documented in `doc/src/fix_nve.txt`)
+  * all new style names should be lower case, the must be no dashes,
+  blanks, or underscores separating words, only forward slashes.
+  * new style docs should be added to the "overview" files in
+  `doc/src/Commands_*.txt`, `doc/src/{fixes,computes,pairs,bonds,...}.txt`
+  and `doc/src/lammps.book`
+  * check whether manual cleanly translates with `make html` and `make pdf`
+  * check spelling of manual with `make spelling` in doc folder
+  * new source files in packages should be added to `src/.gitignore`
+  * removed or renamed files in packages should be added to `src/Purge.list`
+  * C++ source files should use C++ style include files for accessing
+  C-library APIs, e.g. `#include <cstdlib>` instead of `#include <stdlib.h>`.
+  And they should use angular brackets instead of double quotes. Full list:
+    * assert.h -> cassert
+    * ctype.h -> cctype
+    * errno.h -> cerrno
+    * float.h -> cfloat
+    * limits.h -> climits
+    * math.h -> cmath
+    * complex.h -> complex
+    * setjmp.h -> csetjmp
+    * signal.h -> csignal
+    * stddef.h -> cstddef
+    * stdint.h -> cstdint
+    * stdio.h -> cstdio
+    * stdlib.h -> cstdlib
+    * string.h -> cstring
+    * time.h -> ctime
+    * Do NOT replace (as they are C++-11): `inttypes.h` and `stdint.h`.
+  * Code should follow the C++-98 standard. C++-11 is only accepted
+  in individual special purpose packages
+  * indentation is 2 spaces per level
+  * there should be NO tabs and no trailing whitespace
+  * header files, especially of new styles, should not include any
+  other headers, except the header with the base class or cstdio.
+  Forward declarations should be used instead when possible.
+  * iostreams should be avoided. LAMMPS uses stdio from the C-library.
+  * use of STL in headers and class definitions should be avoided.
+  * there MUST NOT be any "using namespace XXX;" statements in headers.
+  * static class members should be avoided at all cost.
+  * anything storing atom IDs should be using `tagint` and not `int`.
+  This can be flagged by the compiler only for pointers and only when
+  compiling LAMMPS with `-DLAMMPS_BIGBIG`.
+  * when including both `lmptype.h` (and using defines or macros from it)
+  and `mpi.h`, `lmptype.h` must be included first.
+  * when pair styles are added, check if settings for flags like
+  `single_enable`, `writedata`, `reinitflag`, `manybody_flag`
+  and others are correctly set and supported.
+
+## GitHub Issues
+
+The GitHub issue tracker is the location where the LAMMPS developers
+and other contributors or LAMMPS users can report issues or bugs with
+the LAMMPS code or request new features to be added. Feature requests
+are usually indicated by a `[Feature Request]` marker in the subject.
+Issues are assigned to a person, if this person is working on this
+feature or working to resolve an issue. Issues that have nobody working
+on them at the moment, have the label `volunteer needed` attached.
+
+When an issue, say `#125` is resolved by a specific pull request,
+the comment for the pull request shall contain the text `closes #125`
+or `fixes #125`, so that the issue is automatically deleted when
+the pull request is merged.
+
+## Milestones and Release Planning
+
+LAMMPS uses a continuous release development model with incremental
+changes, i.e. significant effort is made - including automated pre-merge
+testing - that the code in the branch "master" does not get broken.
+More extensive testing (including regression testing) is performed after
+code is merged to the "master" branch. There are patch releases of
+LAMMPS every 1-3 weeks at a point, when the LAMMPS developers feel, that
+a sufficient amount of changes have happened, and the post-merge testing
+has been successful. These patch releases are marked with a
+`patch_<version date>` tag and the "unstable" branch follows only these
+versions (and thus is always supposed to be of production quality,
+unlike "master", which may be temporary broken, in the case of larger
+change sets or unexpected incompatibilities or side effects.
+
+About 3-4 times each year, there are going to be "stable" releases
+of LAMMPS.  These have seen additional, manual testing and review of
+results from testing with instrumented code and static code analysis.
+Also, in the last 2-3 patch releases before a stable release are
+"release candidate" versions which only contain bugfixes and
+documentation updates.  For release planning and the information of
+code contributors, issues and pull requests being actively worked on
+are assigned a "milestone", which corresponds to the next stable
+release or the stable release after that, with a tentative release
+date.

+# Outline of include file conventions in LAMMPS
+
+This purpose of this document is to provide a point of reference
+for LAMMPS developers and contributors as to what include files
+and definitions to put where into LAMMPS source.
+Last change 2019-07-05
+
+## Table of Contents
+
+  * [Motivation](#motivation)
+  * [Rules](#rules)
+  * [Tools](#tools)
+  * [Legacy Code](#legacy-code)
+
+## Motivation
+
+The conventions outlined in this document are supposed to help make
+maintenance of the LAMMPS software easier.  By trying to achieve
+consistency across files contributed by different developers, it will
+become easier for the code maintainers to modify and adjust files and,
+overall, the chance for errors or portability issues will be reduced.
+The rules employed are supposed to minimize naming conflicts and
+simplify dependencies between files and thus speed up compilation. They
+may, as well, make otherwise hidden dependencies visible.
+
+## Rules
+
+Below are the various rules that are applied.  Not all are enforced
+strictly and automatically.  If there are no significant side effects,
+exceptions may be possible for cases where a full compliance to the
+rules may require a large effort compared to the benefit.
+
+### Core Files Versus Package Files
+
+All rules listed below are most strictly observed for core LAMMPS files,
+which are the files that are not part of a package, and the files of the
+packages MOLECULE, MANYBODY, KSPACE, and RIGID.  On the other end of
+the spectrum are USER packages and legacy packages that predate these
+rules and thus may not be fully compliant.  Also, new contributions
+will be checked more closely, while existing code will be incrementally
+adapted to the rules as time and required effort permits.
+
+### System Versus Local Header Files
+
+All system- or library-provided include files are included with angular
+brackets (examples: `#include <cstring>` or `#include <mpi.h>`) while
+include files provided with LAMMPS are included with double quotes
+(examples: `#include "pointers.h"` or `#include "compute_temp.h"`).
+
+For headers declaring functions of the C-library, the corresponding
+C++ versions should be included (examples: `#include <cstdlib>` or
+`#include <cctypes>`).  However, these includes are limited to those defined
+in the C++98 standard.  Some files thus must use the older style until
+the minimum C++ standard requirement of LAMMPS is lifted to C++11 or
+even beyond (examples: `#include <stdint.h>` versus `#include <cstdint>`
+or `#include <inttypes.h>` versus `#include <cinttypes>`).
+
+### C++ Standard Compliance
+
+LAMMPS core files currently correspond to the C++98 standard. Files
+requiring C++11 or later are only permitted in (optional) packages
+and particularly packages that are not part of the list of commonly
+used packages such as MOLECULE, KSPACE, MANYBODY, or RIGID.
+
+Also, LAMMPS uses the C-style stdio library for I/O instead of iostreams.
+Since using both at the same time can cause problems, iostreams should
+be avoided where possible.
+
+### Lean Header Files
+
+Header files will typically contain the definition of a (single) class.
+These header files should have as few include statements as possible.
+This is particularly important for classes that implement a "style" and
+thus use a macro of the kind `SomeStyle(some/name,SomeName)`. These will
+all be included in the auto-generated `"some_style.h"` files which 
+results in a high potential for direct or indirect symbol name clashes.
+
+In the ideal case, the header would only include one file defining the
+parent class. That would typically be either `#include "pointers.h"` for
+the `Pointers` class, or a header of a class derived from it like
+`#include "pair.h"` for the `Pair` class and so on.  References to other
+classes inside the class should be make through pointers, for which forward
+declarations (inside the `LAMMPS_NS` or the new class' namespace) can
+be employed.  The full definition will then be included into the corresponding
+implementation file.  In the given example from above, the header file
+would be called `some_name.h` and the implementation `some_name.cpp` (all
+lower case with underscores, while the class itself would be in camel case
+and no underscores `SomeName`, and the style name with lower case names separated by
+a forward slash).
+
+### Implementation Files
+
+In the implementation files (typically, those would have the same base name
+as the corresponding header with a .cpp extension instead of .h) include
+statements should follow the "include what you use" principle.
+
+### Order of Include Statements
+
+Include files should be included in this order:
+* the header matching the implementation (`some_class.h` for file `some_class.cpp`)
+* mpi.h
+* system and library headers (anything that is using angular brackets; C-library headers first, then C++)
+* LAMMPS local headers (preferably in alphabetical order)
+
+### Special Cases and Exceptions
+
+#### pointers.h
+
+The `pointer.h` header file also includes `cstdio` and `lmptype.h`
+(and through it `stdint.h`, `intttypes.h`, cstdlib, and `climits`).
+This means any header including `pointers.h` can assume that `FILE`,
+`NULL`, `INT_MAX` are defined.
+
+## Tools
+
+The [Include What You Use tool](https://include-what-you-use.org/)
+can be used to provide supporting information about compliance with
+the rules listed here.  There are some limitations and the IWYU tool
+may give incorrect advice.  The tools is activated by setting the
+CMake variable `CMAKE_CXX_INCLUDE_WHAT_YOU_USE` variable to the
+path of the `include-what-you-use` command.  When activated, the
+tool will be run after each compilation and provide suggestions for
+which include files should be added or removed.
+
+## Legacy Code
+
+A lot of code predates the application of the rules in this document
+and the rules themselves are a moving target.  So there are going to be
+significant chunks of code that do not fully comply.  This applies
+for example to the USER-REAXC, or the USER-ATC package.  The LAMMPS
+developers are dedicated to make an effort to improve the compliance
+and welcome volunteers wanting to help with the process.

+.SH EXECUTABLE NAME
+The

+.B lmp
+or
+.B lmp_<machine name>.
+The <machine name> suffix corresponds to the (machine specific) makefile
+used to compile
+.B LAMMPS
+when using the conventional build process. When building
+.B LAMMPS
+using
+.B CMake
+this <machine name> parameter can be chosen arbitrarily at configuration
+time, but more common is to just use
+.B lmp
+without a suffix. In this manpage we will use
+.B lmp
+to represent any of those names.

-.SH COPYRIGHT 
-© 2003--2018 Sandia Corporation
+.TP
+\fB\-h\fR or \fB\-help\fR
+Print a brief help summary and a list of settings and options compiled
+into this executable. It also explicitly lists all LAMMPS styles
+(atom_style, fix, compute, pair_style, bond_style, etc) available in
+the specific executable. This can tell you if the command you want to
+use was included via the appropriate package at compile time.
+LAMMPS will print the info and immediately exit if this switch is used.
+.TP
+\fB\-e\fR or \fB\-echo\fR
+Set the style of command echoing. The style can be
+.B none
+or
+.B screen
+or
+.B log
+or
+.B both.
+Depending on the style, each command read from the input script will
+be echoed to the screen and/or logfile. This can be useful to figure
+out which line of your script is causing an input error.
+The default value is
+.B log.
+.TP
+\fB\-i <input file>\fR or \fB\-in <input file>\fR
+Specify a file to use as an input script. If it is not specified,
+LAMMPS reads its script from standard input. This is a required
+switch when running LAMMPS in multi-partition mode.
+.TP
+\fB\-k on/off [keyword value]\fR or \fB\-kokkos on/off [keyword value]\fR
+Enable or disable general KOKKOS support, as provided by the KOKKOS
+package.  Even if LAMMPS is built with this package, this switch must
+be set to \fBon\fR to enable running with KOKKOS-enabled styles. More
+details on this switch and its optional keyword value pairs are discussed
+at: https://lammps.sandia.gov/doc/Run_options.html
+.TP
+\fB\-l <log file>\fR or \fB\-log <log file>\fR
+Specify a log file for LAMMPS to write status information to.
+The default value is "log.lammps". If the file name "none" is used,
+\fBLAMMPS\fR will not write a log file. In multi-partition mode only
+some high-level all-partition information is written to the "<log file>"
+file, the remainder is written in a per-partition file "<log file>.N"
+with "N" being the respective partition number, unless overridden
+by the \-plog flag (see below).
+.TP
+\fB\-m <number>\fR or \fB\-mpicolor <number>\fR
+If used, this must be the first command-line argument after the
+.B LAMMPS
+executable name. It is only used when
+.B LAMMPS
+is launched by an mpirun command which also launches one or more
+other executable(s) at the same time.
+.B LAMMPS
+and the other executable(s) perform an MPI_Comm_split(), each with
+their own different colors, to split the MPI_COMM_WORLD communicator
+for each executable to the subset of processors they are supposed to
+be actually running on. Currently, this is only used in
+.B LAMMPS
+to perform client/server messaging with another application.
+.B LAMMPS
+can act as either a client or server (or both).
+.TP
+\fB\-nc\fR or \fB\-nocite\fR
+Disable writing the "log.cite" file which is normally written to
+list references for specific cite-able features used during a
+.B LAMMPS
+run.
+.TP
+\fB\-pk <style> [options]\fR or \fB\-package <style> [options]\fR
+Invoke the \fBpackage\R command with <style> and optional arguments.
+The syntax is the same as if the command appeared in an input script.
+For example "-pk gpu 2" is the same as "package gpu 2" in the input
+script. The possible styles and options are discussed in the
+.B LAMMPS
+manual for the "package" command. This switch can be used multiple
+times, e.g. to set options for the USER-INTEL and USER-OMP packages
+when used together. Along with the "-sf" or "-suffix" switch, this
+is a convenient mechanism for invoking accelerator packages and their
+options without having to edit an input script.
+.TP
+\fB\-p\fR or \fB\-partition\fR
+Invoke
+.B LAMMPS
+in multi-partition mode. Without this,
+.B LAMMPS
+uses all P processors allocated via MPI to run a single simulation.
+If this switch is used, the P processors are split into separate
+partitions and each partition runs its own simulation. The arguments
+to the switch specify the number of processors in each partition.
+Arguments of the form "MxN" mean M partitions, each with N processors.
+Arguments of the form "N" mean a single partition with N processors.
+The sum of processors in all partitions must be equal P. Thus the
+command “-partition 8x2 4 5” has 10 partitions and runs on a total
+of 25 processors.  Running with multiple partitions is required for
+multi-replica simulations, where each replica runs on on one or more
+few processors.
+.TP
+\fB\-pl <basename>\fR or \fB\-plog <basename>\fR
+Specify the base name for the per-partition log files in multi-partition
+runs, where partition N writes log information to <basename>.N.
+If basename is set to "none", then no per-partition log files are created.
+This overrides the name specified in the \-log command-line option.
+.TP
+\fB\-ps <basename>\fR or \fB\-pscreen <basename>\fR
+Specify the base name for the per-partition screen files in multi-partition
+runs, where partition N writes screen output to <basename>.N.
+If basename is set to "none", then no per-partition screen files are created.
+The default value is "screen" or whatever is set by the \-screen flag.
+.TP
+\fB\-r2data <restart file> [remap] <data file>\fR or
+\fB\-restart2data <restart file> [remap] <data file>\fR
+Convert <restart file> previously written by
+.B LAMMPS
+into a data file and immediately exit. This option has replaced the
+external restart2data executable. Following <restart file>
+argument, the optional word "remap" may be used. This has the
+same effect like adding it to a "read_restart" command.
+The syntax following the <data file> name is identical to the
+arguments of the "write_data" command. See the
+.B LAMMPS
+manual for details on either of the two commands.
+.TP
+\fB\-r2dump <restart file> [remap] <dump file>\fR or
+\fB\-restart2dump <restart file> [remap] <dump file>\fR
+Convert <restart file> previously written by
+.B LAMMPS
+into a dump file and immediately exit. Following <restart file>
+argument, the optional word "remap" may be used. This has the
+same effect like adding it to a "read_restart" command.
+The syntax following the <dump file> name is identical to the
+arguments of the "dump" command. See the
+.B LAMMPS
+manual for details on either of the two commands.
+.TP
+\fB\-sc <file name>\fR or \fB\-screen <file name>\fR
+Specify a file for
+.B LAMMPS
+to write its screen information to. By default, this will be
+the standard output. If <file name> is "none", (most) screen
+output will be suppressed.  In multi-partition mode only
+some high-level all-partition information is written to the
+screen or "<file name>" file, the remainder is written in a
+per-partition file "screen.N" or "<file name>.N" 
+with "N" being the respective partition number, and unless
+overridden by the \-pscreen flag (see above).
+.TP
+\fB\-sf <suffix>\fR or \fB\-suffix <suffix>\fR
+Use variants of various styles in the input, if they exist. This is
+achieved by transparently trying to convert a style named <my/style>
+into <my/style/suffix> if that latter style exists, but otherwise
+fall back to the former. The most useful suffixes are  "gpu",
+"intel", "kk", "omp", "opt", or "hybrid". These refer to styles from
+optional packages that LAMMPS can be built with. The hybrid suffix is
+special, as it enables, having two suffixes tried (e.g. first "intel"
+and then "omp") and thus requires two arguments. Along with the
+"-package" command-line switch, this is a convenient mechanism for
+invoking styles from accelerator packages and setting their options
+without having to edit an input script.
+
+See https://lammps.sandia.gov/doc/Run_options.html for additional
+details and discussions on command-line options.
+
+.SH LAMMPS BASICS
+LAMMPS executes by reading commands from a input script (text file),
+one line at a time.  When the input script ends, LAMMPS exits.  Each
+command causes LAMMPS to take some action.  It may set or change an
+internal, read and parse a file, or run a simulation.  Most commands
+have default settings, which means you only need to use the command
+if you wish to change the default.
+
+The ordering of commands in an input script is usually not very important
+unless a command like "run" is encountered, which starts some calculation
+using the current internal state. Also, if a "pair_style" or "bond_style"
+other similar style command is issued that has a different name from what
+was previously active, it will replace the previous style and wipe out
+all corresponding "pair_coeff" or "bond_coeff" or equivalent settings.
+Some commands are only valid when they follow other commands.  For
+example you cannot set the temperature of a group of atoms until atoms
+have been defined and a group command is used to define which atoms
+belong to the group of a given name. Sometimes command B will use values
+that can be set by command A. This means command A must precede command
+B in the input to have the desired effect. Some commands must be issued
+.B before
+the simulation box is defined and others can only be issued
+.B after.
+Many input script errors are detected by
+.B LAMMPS
+and an ERROR or WARNING message is printed.  The documentation for
+each command lists restrictions on how the command can be used, and
+the chapter on errors in the
+.B LAMMPS
+manual gives some additional information about error messages, if possible.

+.TH MSI2LMP "v3.9.9" "2018-11-05"
+.SH NAME
+.B MSI2LMP
+\- Converter for Materials Studio files to LAMMPS
+
+.SH SYNOPSIS
+.B msi2lmp
+<ROOTNAME> [-class <I|1|II|2|O|0>] [-frc <path to frc file>] [-print #] [-ignore] [-nocenter] [-oldstyle] [-shift <x> <y> <z>]
+
+.SH DESCRIPTION
+.PP
+.B MSI2LMP
+is a tool bundled with LAMMPS to aide in the conversion of simulation
+inputs from Biovia's Materials Studio software for use with LAMMPS.
+It is a standalone program that generates a LAMMPS data file based on
+the information in an MS .car file (atom coordinates), an .mdf file
+(molecular topology and atom types) and an .frc (forcefield parameters)
+file.  The .car and .mdf files are specific to a molecular system while
+the .frc file is specific to a forcefield (variant).  The only coherency
+needed between .frc and .car/.mdf files are the atom types.
+.PP
+
+.SH OPTIONS
+.TP
+\fB\<ROOTNAME>\fR
+This has to be the first argument and is a
+.B mandatory
+argument. It defines the root of the file names; i.e. for a
+.B <ROOTNAME>
+of benzene, you have to provide the files 'benzene.car' and 'benzene.mdf'
+in the current working directory.
+.B msi2lmp
+will then read and process those files according to its remaining settings.
+All other settins are optional and have defaults as listed.
+.TP
+\fB\-c <I,1,II,2,O,0>\fR, \fB\-class <I,1,II,2,O,0>\fR
+The \-c or \-class option selects the force field class, i.e which pair
+styles and bond styles and so on are required in the LAMMPS input file.
+Class I or class 1 uses similar combination of functional forms as Amber
+and Charmm force field and support the force fields 
+.B cvff
+and
+.B clayff.
+Class II or class 2 corresponds to the more complex force fields
+.B COMPASS
+and
+.B pcff.
+Class O or class 0 finally is an experimental and incomplete extension
+and supports generating output for
+.B OPLS-AA
+.TP
+\fB\-f <ffname>\fR, \fB\-frc <ffname>\fR
+The \-c or \-frc option allows the selection of the force field parameter
+file
+.B<ffname>.frc.
+Valid names for <ffname> with this distribution are: cvff, clayff, cvff_aug,
+pcff, compass_published, cff91, and oplsaa. If the argument is a pathname,
+i.e. it starts with a '.' or a '/', then this absolute path is used to read
+the force field, otherwise
+.B msi2lmp
+will look in the folder pointed to by the environment variable
+$MSI2LMP_LIBRARY. If the variable is not set, then it will look in the current
+directory. The extension '.frc' is appended, if missing.
+Default is to look for the cvff.frc force field file.
+.TP
+\fB\-p <loglevel>\fR, \fB\-print <loglevel>\fR,
+Selects the amount of information messages about the progress of the
+conversion printed to the screen.
+.B <loglevel>
+can be a number from 0 (silent except for errors) to 3 (very detailed).
+.TP
+\fB\-i\fR, \fB\-ignore\fR,
+Ignore errors about missing parameters and use 0.0 for the respective
+force constants making these no-ops. Is correct to be used for a few
+molecules and settings, but often an indication, that either the atom
+type assignment have errors, or the force field file is missing entries.
+.TP
+\fB\-n\fR, \fB\-nocenter\fR,
+Do not center the box around the (geometrical) center of the atoms,
+but around the origin. Default is to recenter.
+.TP
+\fB\-o\fR, \fB\-oldstyle\fR,
+Write out a data file without style hint comments to be compatible
+with old LAMMPS versions. Default is to write out those comments.
+.TP
+\fB-s <x> <y> <z>\fR, \fB-shift <x> <y> <z>\fR,
+Shift the entire system (box and coordinates) by a vector
+(default: 0.0 0.0 0.0).
+.TP
+
+.SH EXAMPLES
+
+msi2lmp benzene -c 2 -p 1 -f ../frc_files/pcff.frc
+
+msi2lmp benzene-class1 -c I
+
+msi2lmp decane -c 0 -f oplsaa

+USER-PLUMED package :h4,link(user-plumed)
+
+Before building LAMMPS with this package, you must first build PLUMED.
+PLUMED can be built as part of the LAMMPS build or installed separately
+from LAMMPS using the generic "plumed installation instructions"_plumedinstall.
+:link(plumedinstall,http://plumed.github.io/doc-master/user-doc/html/_installation.html)
+
+PLUMED can be linked into MD codes in three different modes: static,
+shared, and runtime.  With the "static" mode, all the code that PLUMED
+requires is linked statically into LAMMPS. LAMMPS is then fully
+independent from the PLUMED installation, but you have to rebuild/relink
+it in order to update the PLUMED code inside it.  With the "shared"
+linkage mode, LAMMPS is linked to a shared library that contains the
+PLUMED code.  This library should preferably be installed in a globally
+accessible location. When PLUMED is linked in this way the same library
+can be used by multiple MD packages.  Furthermore, the PLUMED library
+LAMMPS uses can be updated without the need for a recompile of LAMMPS
+for as long as the shared PLUMED library is ABI-compatible.
+
+The third linkage mode is "runtime" which allows the user to specify
+which PLUMED kernel should be used at runtime by using the PLUMED_KERNEL
+environment variable. This variable should point to the location of the
+libplumedKernel.so dynamical shared object, which is then loaded at
+runtime. This mode of linking is particularly convenient for doing
+PLUMED development and comparing multiple PLUMED versions as these sorts
+of comparisons can be done without recompiling the hosting MD code. All
+three linkage modes are supported by LAMMPS on selected operating
+systems (e.g. Linux) and using either CMake or traditional make
+build. The "static" mode should be the most portable, while the
+"runtime" mode support in LAMMPS makes the most assumptions about
+operating system and compiler environment. If one mode does not work,
+try a different one, switch to a different build system, consider a
+global PLUMED installation or consider downloading PLUMED during the
+LAMMPS build.
+
+[CMake build]:
+
+When the "-D PKG_USER-PLUMED" flag is included in the cmake command you
+must ensure that GSL is installed in locations that are specified in
+your environment.  There are then two additional commands that control
+the manner in which PLUMED is obtained and linked into LAMMPS.
+
+-D DOWNLOAD_PLUMED=value   # download PLUMED for build, value = no (default) or yes
+-D PLUMED_MODE=value       # Linkage mode for PLUMED, value = static (default), shared, or runtime :pre
+
+If DOWNLOAD_PLUMED is set to "yes", the PLUMED library will be
+downloaded (the version of PLUMED that will be downloaded is hard-coded
+to a vetted version of PLUMED, usually a recent stable release version)
+and built inside the CMake build directory.  If DOWNLOAD_PLUMED is set
+to "no" (the default), CMake will try to detect and link to an installed
+version of PLUMED.  For this to work, the PLUMED library has to be
+installed into a location where the pkg-config tool can find it or the
+PKG_CONFIG_PATH environment variable has to be set up accordingly.
+PLUMED should be installed in such a location if you compile it using
+the default make; make install commands.
+
+The PLUMED_MODE setting determines the linkage mode for the PLUMED
+library.  The allowed values for this flag are "static" (default),
+"shared", or "runtime".  For a discussion of PLUMED linkage modes,
+please see above.  When DOWNLOAD_PLUMED is enabled the static linkage
+mode is recommended.
+
+[Traditional make]:
+
+PLUMED needs to be installed before the USER-PLUMED package is installed
+so that LAMMPS can find the right settings when compiling and linking
+the LAMMPS executable.  You can either download and build PLUMED inside
+the LAMMPS plumed library folder or use a previously installed PLUMED
+library and point LAMMPS to its location. You also have to choose the
+linkage mode: "static" (default), "shared" or "runtime".  For a
+discussion of PLUMED linkage modes, please see above.
+
+Download/compilation/configuration of the plumed library can be done
+from the src folder through the following make args:
+
+make lib-plumed                         # print help message
+make lib-plumed args="-b"               # download and build PLUMED in lib/plumed/plumed2
+make lib-plumed args="-p $HOME/.local"  # use existing PLUMED installation in $HOME/.local
+make lib-plumed args="-p /usr/local -m shared"  # use existing PLUMED installation in
+                                                # /usr/local and use shared linkage mode
+:pre
+
+Note that 2 symbolic (soft) links, "includelink" and "liblink" are
+created in lib/plumed that point to the location of the PLUMED build to
+use. A new file lib/plumed/Makefile.lammps is also created with settings
+suitable for LAMMPS to compile and link PLUMED using the desired linkage
+mode. After this step is completed, you can install the USER-PLUMED
+package and compile LAMMPS in the usual manner:
+
+make yes-user-plumed
+make machine :pre
+
+Once this compilation completes you should be able to run LAMMPS in the
+usual way.  For shared linkage mode, libplumed.so must be found by the
+LAMMPS executable, which on many operating systems means, you have to
+set the LD_LIBRARY_PATH environment variable accordingly.
+
+Support for the different linkage modes in LAMMPS varies for different
+operating systems, using the static linkage is expected to be the most
+portable, and thus set to be the default.
+
+If you want to change the linkage mode, you have to re-run "make
+lib-plumed" with the desired settings [and] do a re-install if the
+USER-PLUMED package with "make yes-user-plumed" to update the required
+makefile settings with the changes in the lib/plumed folder.

+Removed commands and packages :h3
+
+This page lists LAMMPS commands and packages that have been removed from
+the distribution and provides suggestions for alternatives or replacements.
+LAMMPS has special dummy styles implemented, that will stop LAMMPS and
+print a suitable error message in most cases, when a style/command is used
+that has been removed.
+
+Fix ave/spatial and fix ave/spatial/sphere :h4
+
+The fixes ave/spatial and ave/spatial/sphere have been removed from LAMMPS
+since they were superseded by the more general and extensible "chunk
+infrastructure".  Here the system is partitioned in one of many possible
+ways through the "compute chunk/atom"_compute_chunk_atom.html command
+and then averaging is done using "fix ave/chunk"_fix_ave_chunk.html.
+Please refer to the "chunk HOWTO"_Howto_chunk.html section for an overview.
+
+MEAM package :h4
+
+The MEAM package has been removed since it was superseded by the
+"USER-MEAMC package"_Package_details.html#PKG-USER-MEAMC. The code in
+the USER-MEAMC package is a translation of the Fortran code of MEAM into C++,
+which removes several restrictions (e.g. there can be multiple instances
+in hybrid pair styles) and allows for some optimizations leading
+to better performance.  The new pair style "meam/c"_pair_meamc.html has
+the exact same syntax as the old "meam" pair style and thus pair style
+"meam"_pair_meamc.html is an alias to the new style and backward
+compatibility of old inputs is preserved.
+
+REAX package :h4
+
+The REAX package has been removed since it was superseded by the
+"USER-REAXC package"_Package_details.html#PKG-USER-REAXC.  The USER-REAXC
+package has been tested to yield equivalent results to the REAX package,
+offers better performance, supports OpenMP multi-threading via USER-OMP,
+and GPU and threading parallelization through KOKKOS.  The new pair styles
+are not syntax compatible with the removed reax pair style, so input
+files will have to be adapted.
+
+USER-CUDA package :h4
+
+The USER-CUDA package had been removed, since it had been unmaintained
+for a long time and had known bugs and problems.  Significant parts of
+the design were transferred to the
+"KOKKOS package"_Package_details.html#PKG-KOKKOS, which has similar
+performance characteristics on Nvidia GPUs. Both, the KOKKOS
+and the "GPU package"_Package_details.html#PKG-GPU are maintained
+and allow running LAMMPS with GPU acceleration.
+
+restart2data tool :h4
+
+The functionality of the restart2data tool has been folded into the
+LAMMPS executable directly instead of having a separate tool.  A
+combination of the commands "read_restart"_read_restart.html and
+"write_data"_write_data.html can be used to the same effect.  For added
+convenience this conversion can also be triggered by "command line
+flags"_Run_options.html
