+[verse]
+'git p4 clone' [<sync-options>] [<clone-options>] <p4-depot-path>...
+'git p4 sync' [<sync-options>] [<p4-depot-path>...]

+
+
+DESCRIPTION
+-----------
+This command provides a way to interact with p4 repositories
+using Git.
+
+Create a new Git repository from an existing p4 repository using
+'git p4 clone', giving it one or more p4 depot paths. Incorporate
+new commits from p4 changes with 'git p4 sync'. The 'sync' command
+is also used to include new branches from other p4 depot paths.
+Submit Git changes back to p4 using 'git p4 submit'. The command
+'git p4 rebase' does a sync plus rebases the current branch onto
+the updated p4 remote branch.
+
+
+EXAMPLES
+--------
+* Clone a repository:
++
+------------
+$ git p4 clone //depot/path/project
+------------
+
+* Do some work in the newly created Git repository:
++
+------------
+$ cd project
+$ vi foo.h
+$ git commit -a -m "edited foo.h"
+------------
+
+* Update the Git repository with recent changes from p4, rebasing your
+ work on top:
++
+------------
+$ git p4 rebase
+------------
+
+* Submit your commits back to p4:
++
+------------
+$ git p4 submit
+------------
+
+
+COMMANDS
+--------
+
+Clone
+~~~~~
+Generally, 'git p4 clone' is used to create a new Git directory
+from an existing p4 repository:
+------------
+$ git p4 clone //depot/path/project
+------------
+This:
+
+1. Creates an empty Git repository in a subdirectory called 'project'.
++
+2. Imports the full contents of the head revision from the given p4
+ depot path into a single commit in the Git branch 'refs/remotes/p4/master'.
++
+3. Creates a local branch, 'master' from this remote and checks it out.
+
+To reproduce the entire p4 history in Git, use the '@all' modifier on
+the depot path:
+------------
+$ git p4 clone //depot/path/project@all
+------------
+
+
+Sync
+~~~~
+As development continues in the p4 repository, those changes can
+be included in the Git repository using:
+------------
+$ git p4 sync
+------------
+This command finds new changes in p4 and imports them as Git commits.
+
+P4 repositories can be added to an existing Git repository using
+'git p4 sync' too:
+------------
+$ mkdir repo-git
+$ cd repo-git
+$ git init
+$ git p4 sync //path/in/your/perforce/depot
+------------
+This imports the specified depot into
+'refs/remotes/p4/master' in an existing Git repository. The
+`--branch` option can be used to specify a different branch to
+be used for the p4 content.
+
+If a Git repository includes branches 'refs/remotes/origin/p4', these
+will be fetched and consulted first during a 'git p4 sync'. Since
+importing directly from p4 is considerably slower than pulling changes
+from a Git remote, this can be useful in a multi-developer environment.
+
+If there are multiple branches, doing 'git p4 sync' will automatically
+use the "BRANCH DETECTION" algorithm to try to partition new changes
+into the right branch. This can be overridden with the `--branch`
+option to specify just a single branch to update.
+
+
+Rebase
+~~~~~~
+A common working pattern is to fetch the latest changes from the p4 depot
+and merge them with local uncommitted changes. Often, the p4 repository
+is the ultimate location for all code, thus a rebase workflow makes
+sense. This command does 'git p4 sync' followed by 'git rebase' to move
+local commits on top of updated p4 changes.
+------------
+$ git p4 rebase
+------------
+
+
+Submit
+~~~~~~
+Submitting changes from a Git repository back to the p4 repository
+requires a separate p4 client workspace. This should be specified
+using the `P4CLIENT` environment variable or the Git configuration
+variable 'git-p4.client'. The p4 client must exist, but the client root
+will be created and populated if it does not already exist.
+
+To submit all changes that are in the current Git branch but not in
+the 'p4/master' branch, use:
+------------
+$ git p4 submit
+------------
+
+To specify a branch other than the current one, use:
+------------
+$ git p4 submit topicbranch
+------------
+
+To specify a single commit or a range of commits, use:
+------------
+$ git p4 submit --commit <sha1>
+$ git p4 submit --commit <sha1..sha1>
+------------
+
+The upstream reference is generally 'refs/remotes/p4/master', but can
+be overridden using the `--origin=` command-line option.
+
+The p4 changes will be created as the user invoking 'git p4 submit'. The
+`--preserve-user` option will cause ownership to be modified
+according to the author of the Git commit. This option requires admin
+privileges in p4, which can be granted using 'p4 protect'.
+
+To shelve changes instead of submitting, use `--shelve` and `--update-shelve`:
+
+----
+$ git p4 submit --shelve
+$ git p4 submit --update-shelve 1234 --update-shelve 2345
+----
+
+
+Unshelve
+~~~~~~~~
+Unshelving will take a shelved P4 changelist, and produce the equivalent git commit
+in the branch refs/remotes/p4-unshelved/<changelist>.
+
+The git commit is created relative to the current origin revision (HEAD by default).
+A parent commit is created based on the origin, and then the unshelve commit is
+created based on that.
+
+The origin revision can be changed with the "--origin" option.
+
+If the target branch in refs/remotes/p4-unshelved already exists, the old one will
+be renamed.
+
+----
+$ git p4 sync
+$ git p4 unshelve 12345
+$ git show p4-unshelved/12345
+<submit more changes via p4 to the same files>
+$ git p4 unshelve 12345
+<refuses to unshelve until git is in sync with p4 again>
+
+----
+
+OPTIONS
+-------
+
+General options
+~~~~~~~~~~~~~~~
+All commands except clone accept these options.
+
+--git-dir <dir>::
+ Set the `GIT_DIR` environment variable. See linkgit:git[1].
+
+-v::
+--verbose::
+ Provide more progress information.
+
+Sync options
+~~~~~~~~~~~~
+These options can be used in the initial 'clone' as well as in
+subsequent 'sync' operations.
+
+--branch <ref>::
+ Import changes into <ref> instead of refs/remotes/p4/master.
+ If <ref> starts with refs/, it is used as is. Otherwise, if
+ it does not start with p4/, that prefix is added.
++
+By default a <ref> not starting with refs/ is treated as the
+name of a remote-tracking branch (under refs/remotes/). This
+behavior can be modified using the --import-local option.
++
+The default <ref> is "master".
++
+This example imports a new remote "p4/proj2" into an existing
+Git repository:
++
+----
+ $ git init
+ $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
+----
+
+--detect-branches::
+ Use the branch detection algorithm to find new paths in p4. It is
+ documented below in "BRANCH DETECTION".
+
+--changesfile <file>::
+ Import exactly the p4 change numbers listed in 'file', one per
+ line. Normally, 'git p4' inspects the current p4 repository
+ state and detects the changes it should import.
+
+--silent::
+ Do not print any progress information.
+
+--detect-labels::
+ Query p4 for labels associated with the depot paths, and add
+ them as tags in Git. Limited usefulness as only imports labels
+ associated with new changelists. Deprecated.
+
+--import-labels::
+ Import labels from p4 into Git.
+
+--import-local::
+ By default, p4 branches are stored in 'refs/remotes/p4/',
+ where they will be treated as remote-tracking branches by
+ linkgit:git-branch[1] and other commands. This option instead
+ puts p4 branches in 'refs/heads/p4/'. Note that future
+ sync operations must specify `--import-local` as well so that
+ they can find the p4 branches in refs/heads.
+
+--max-changes <n>::
+ Import at most 'n' changes, rather than the entire range of
+ changes included in the given revision specifier. A typical
+ usage would be use '@all' as the revision specifier, but then
+ to use '--max-changes 1000' to import only the last 1000
+ revisions rather than the entire revision history.
+
+--changes-block-size <n>::
+ The internal block size to use when converting a revision
+ specifier such as '@all' into a list of specific change
+ numbers. Instead of using a single call to 'p4 changes' to
+ find the full list of changes for the conversion, there are a
+ sequence of calls to 'p4 changes -m', each of which requests
+ one block of changes of the given size. The default block size
+ is 500, which should usually be suitable.
+
+--keep-path::
+ The mapping of file names from the p4 depot path to Git, by
+ default, involves removing the entire depot path. With this
+ option, the full p4 depot path is retained in Git. For example,
+ path '//depot/main/foo/bar.c', when imported from
+ '//depot/main/', becomes 'foo/bar.c'. With `--keep-path`, the
+ Git path is instead 'depot/main/foo/bar.c'.
+
+--use-client-spec::
+ Use a client spec to find the list of interesting files in p4.
+ See the "CLIENT SPEC" section below.
+
+-/ <path>::
+ Exclude selected depot paths when cloning or syncing.
+
+Clone options
+~~~~~~~~~~~~~
+These options can be used in an initial 'clone', along with the 'sync'
+options described above.
+
+--destination <directory>::
+ Where to create the Git repository. If not provided, the last
+ component in the p4 depot path is used to create a new
+ directory.
+
+--bare::
+ Perform a bare clone. See linkgit:git-clone[1].
+
+Submit options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 submit' behavior.
+
+--origin <commit>::
+ Upstream location from which commits are identified to submit to
+ p4. By default, this is the most recent p4 commit reachable
+ from `HEAD`.
+
+-M::
+ Detect renames. See linkgit:git-diff[1]. Renames will be
+ represented in p4 using explicit 'move' operations. There
+ is no corresponding option to detect copies, but there are
+ variables for both moves and copies.
+
+--preserve-user::
+ Re-author p4 changes before submitting to p4. This option
+ requires p4 admin privileges.
+
+--export-labels::
+ Export tags from Git as p4 labels. Tags found in Git are applied
+ to the perforce working directory.
+
+-n::
+--dry-run::
+ Show just what commits would be submitted to p4; do not change
+ state in Git or p4.
+
+--prepare-p4-only::
+ Apply a commit to the p4 workspace, opening, adding and deleting
+ files in p4 as for a normal submit operation. Do not issue the
+ final "p4 submit", but instead print a message about how to
+ submit manually or revert. This option always stops after the
+ first (oldest) commit. Git tags are not exported to p4.
+
+--shelve::
+ Instead of submitting create a series of shelved changelists.
+ After creating each shelve, the relevant files are reverted/deleted.
+ If you have multiple commits pending multiple shelves will be created.
+
+--update-shelve CHANGELIST::
+ Update an existing shelved changelist with this commit. Implies
+ --shelve. Repeat for multiple shelved changelists.
+
+--conflict=(ask|skip|quit)::
+ Conflicts can occur when applying a commit to p4. When this
+ happens, the default behavior ("ask") is to prompt whether to
+ skip this commit and continue, or quit. This option can be used
+ to bypass the prompt, causing conflicting commits to be automatically
+ skipped, or to quit trying to apply commits, without prompting.
+
+--branch <branch>::
+ After submitting, sync this named branch instead of the default
+ p4/master. See the "Sync options" section above for more
+ information.
+
+--commit (<sha1>|<sha1>..<sha1>)::
+ Submit only the specified commit or range of commits, instead of the full
+ list of changes that are in the current Git branch.
+
+--disable-rebase::
+ Disable the automatic rebase after all commits have been successfully
+ submitted. Can also be set with git-p4.disableRebase.
+
+--disable-p4sync::
+ Disable the automatic sync of p4/master from Perforce after commits have
+ been submitted. Implies --disable-rebase. Can also be set with
+ git-p4.disableP4Sync. Sync with origin/master still goes ahead if possible.
+
+Hooks for submit
+----------------
+
+p4-pre-submit
+~~~~~~~~~~~~~
+
+The `p4-pre-submit` hook is executed if it exists and is executable.
+The hook takes no parameters and nothing from standard input. Exiting with
+non-zero status from this script prevents `git-p4 submit` from launching.
+It can be bypassed with the `--no-verify` command line option.
+
+One usage scenario is to run unit tests in the hook.
+
+p4-prepare-changelist
+~~~~~~~~~~~~~~~~~~~~~
+
+The `p4-prepare-changelist` hook is executed right after preparing
+the default changelist message and before the editor is started.
+It takes one parameter, the name of the file that contains the
+changelist text. Exiting with a non-zero status from the script
+will abort the process.
+
+The purpose of the hook is to edit the message file in place,
+and it is not suppressed by the `--no-verify` option. This hook
+is called even if `--prepare-p4-only` is set.
+
+p4-changelist
+~~~~~~~~~~~~~
+
+The `p4-changelist` hook is executed after the changelist
+message has been edited by the user. It can be bypassed with the
+`--no-verify` option. It takes a single parameter, the name
+of the file that holds the proposed changelist text. Exiting
+with a non-zero status causes the command to abort.
+
+The hook is allowed to edit the changelist file and can be used
+to normalize the text into some project standard format. It can
+also be used to refuse the Submit after inspect the message file.
+
+p4-post-changelist
+~~~~~~~~~~~~~~~~~~
+
+The `p4-post-changelist` hook is invoked after the submit has
+successfully occurred in P4. It takes no parameters and is meant
+primarily for notification and cannot affect the outcome of the
+git p4 submit action.
+
+
+
+Rebase options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 rebase' behavior.
+
+--import-labels::
+ Import p4 labels.
+
+Unshelve options
+~~~~~~~~~~~~~~~~
+
+--origin::
+ Sets the git refspec against which the shelved P4 changelist is compared.
+ Defaults to p4/master.
+
+DEPOT PATH SYNTAX
+-----------------
+The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
+be one or more space-separated p4 depot paths, with an optional
+p4 revision specifier on the end:
+
+"//depot/my/project"::
+ Import one commit with all files in the '#head' change under that tree.
+
+"//depot/my/project@all"::
+ Import one commit for each change in the history of that depot path.
+
+"//depot/my/project@1,6"::
+ Import only changes 1 through 6.
+
+"//depot/proj1@all //depot/proj2@all"::
+ Import all changes from both named depot paths into a single
+ repository. Only files below these directories are included.
+ There is not a subdirectory in Git for each "proj1" and "proj2".
+ You must use the `--destination` option when specifying more
+ than one depot path. The revision specifier must be specified
+ identically on each depot path. If there are files in the
+ depot paths with the same name, the path with the most recently
+ updated version of the file is the one that appears in Git.
+
+See 'p4 help revisions' for the full syntax of p4 revision specifiers.
+
+
+CLIENT SPEC
+-----------
+The p4 client specification is maintained with the 'p4 client' command
+and contains among other fields, a View that specifies how the depot
+is mapped into the client repository. The 'clone' and 'sync' commands
+can consult the client spec when given the `--use-client-spec` option or
+when the useClientSpec variable is true. After 'git p4 clone', the
+useClientSpec variable is automatically set in the repository
+configuration file. This allows future 'git p4 submit' commands to
+work properly; the submit command looks only at the variable and does
+not have a command-line option.
+
+The full syntax for a p4 view is documented in 'p4 help views'. 'git p4'
+knows only a subset of the view syntax. It understands multi-line
+mappings, overlays with '+', exclusions with '-' and double-quotes
+around whitespace. Of the possible wildcards, 'git p4' only handles
+'...', and only when it is at the end of the path. 'git p4' will complain
+if it encounters an unhandled wildcard.
+
+Bugs in the implementation of overlap mappings exist. If multiple depot
+paths map through overlays to the same location in the repository,
+'git p4' can choose the wrong one. This is hard to solve without
+dedicating a client spec just for 'git p4'.
+
+The name of the client can be given to 'git p4' in multiple ways. The
+variable 'git-p4.client' takes precedence if it exists. Otherwise,
+normal p4 mechanisms of determining the client are used: environment
+variable `P4CLIENT`, a file referenced by `P4CONFIG`, or the local host name.
+
+
+BRANCH DETECTION
+----------------
+P4 does not have the same concept of a branch as Git. Instead,
+p4 organizes its content as a directory tree, where by convention
+different logical branches are in different locations in the tree.
+The 'p4 branch' command is used to maintain mappings between
+different areas in the tree, and indicate related content. 'git p4'
+can use these mappings to determine branch relationships.
+
+If you have a repository where all the branches of interest exist as
+subdirectories of a single depot path, you can use `--detect-branches`
+when cloning or syncing to have 'git p4' automatically find
+subdirectories in p4, and to generate these as branches in Git.
+
+For example, if the P4 repository structure is:
+----
+//depot/main/...
+//depot/branch1/...
+----
+
+And "p4 branch -o branch1" shows a View line that looks like:
+----
+//depot/main/... //depot/branch1/...
+----
+
+Then this 'git p4 clone' command:
+----
+git p4 clone --detect-branches //depot@all
+----
+produces a separate branch in 'refs/remotes/p4/' for //depot/main,
+called 'master', and one for //depot/branch1 called 'depot/branch1'.
+
+However, it is not necessary to create branches in p4 to be able to use
+them like branches. Because it is difficult to infer branch
+relationships automatically, a Git configuration setting
+'git-p4.branchList' can be used to explicitly identify branch
+relationships. It is a list of "source:destination" pairs, like a
+simple p4 branch specification, where the "source" and "destination" are
+the path elements in the p4 repository. The example above relied on the
+presence of the p4 branch. Without p4 branches, the same result will
+occur with:
+----
+git init depot
+cd depot
+git config git-p4.branchList main:branch1
+git p4 clone --detect-branches //depot@all .
+----
+
+
+PERFORMANCE
+-----------
+The fast-import mechanism used by 'git p4' creates one pack file for
+each invocation of 'git p4 sync'. Normally, Git garbage compression
+(linkgit:git-gc[1]) automatically compresses these to fewer pack files,
+but explicit invocation of 'git repack -adf' may improve performance.
+
+
+CONFIGURATION VARIABLES
+-----------------------
+The following config settings can be used to modify 'git p4' behavior.
+They all are in the 'git-p4' section.
+
+General variables
+~~~~~~~~~~~~~~~~~
+git-p4.user::
+ User specified as an option to all p4 commands, with '-u <user>'.
+ The environment variable `P4USER` can be used instead.
+
+git-p4.password::
+ Password specified as an option to all p4 commands, with
+ '-P <password>'.
+ The environment variable `P4PASS` can be used instead.
+
+git-p4.port::
+ Port specified as an option to all p4 commands, with
+ '-p <port>'.
+ The environment variable `P4PORT` can be used instead.
+
+git-p4.host::
+ Host specified as an option to all p4 commands, with
+ '-h <host>'.
+ The environment variable `P4HOST` can be used instead.
+
+git-p4.client::
+ Client specified as an option to all p4 commands, with
+ '-c <client>', including the client spec.
+
+git-p4.retries::
+ Specifies the number of times to retry a p4 command (notably,
+ 'p4 sync') if the network times out. The default value is 3.
+ Set the value to 0 to disable retries or if your p4 version
+ does not support retries (pre 2012.2).
+
+Clone and sync variables
+~~~~~~~~~~~~~~~~~~~~~~~~
+git-p4.syncFromOrigin::
+ Because importing commits from other Git repositories is much faster
+ than importing them from p4, a mechanism exists to find p4 changes
+ first in Git remotes. If branches exist under 'refs/remote/origin/p4',
+ those will be fetched and used when syncing from p4. This
+ variable can be set to 'false' to disable this behavior.
+
+git-p4.branchUser::
+ One phase in branch detection involves looking at p4 branches
+ to find new ones to import. By default, all branches are
+ inspected. This option limits the search to just those owned
+ by the single user named in the variable.
+
+git-p4.branchList::
+ List of branches to be imported when branch detection is
+ enabled. Each entry should be a pair of branch names separated
+ by a colon (:). This example declares that both branchA and
+ branchB were created from main:
++
+-------------
+git config git-p4.branchList main:branchA
+git config --add git-p4.branchList main:branchB
+-------------
+
+git-p4.ignoredP4Labels::
+ List of p4 labels to ignore. This is built automatically as
+ unimportable labels are discovered.
+
+git-p4.importLabels::
+ Import p4 labels into git, as per --import-labels.
+
+git-p4.labelImportRegexp::
+ Only p4 labels matching this regular expression will be imported. The
+ default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.useClientSpec::
+ Specify that the p4 client spec should be used to identify p4
+ depot paths of interest. This is equivalent to specifying the
+ option `--use-client-spec`. See the "CLIENT SPEC" section above.
+ This variable is a boolean, not the name of a p4 client.
+
+git-p4.pathEncoding::
+ Perforce keeps the encoding of a path as given by the originating OS.
+ Git expects paths encoded as UTF-8. Use this config to tell git-p4
+ what encoding Perforce had used for the paths. This encoding is used
+ to transcode the paths to UTF-8. As an example, Perforce on Windows
+ often uses "cp1252" to encode path names. If this option is passed
+ into a p4 clone request, it is persisted in the resulting new git
+ repo.
+
+git-p4.metadataDecodingStrategy::
+ Perforce keeps the encoding of a changelist descriptions and user
+ full names as stored by the client on a given OS. The p4v client
+ uses the OS-local encoding, and so different users can end up storing
+ different changelist descriptions or user full names in different
+ encodings, in the same depot.
+ Git tolerates inconsistent/incorrect encodings in commit messages
+ and author names, but expects them to be specified in utf-8.
+ git-p4 can use three different decoding strategies in handling the
+ encoding uncertainty in Perforce: 'passthrough' simply passes the
+ original bytes through from Perforce to git, creating usable but
+ incorrectly-encoded data when the Perforce data is encoded as
+ anything other than utf-8. 'strict' expects the Perforce data to be
+ encoded as utf-8, and fails to import when this is not true.
+ 'fallback' attempts to interpret the data as utf-8, and otherwise
+ falls back to using a secondary encoding - by default the common
+ windows encoding 'cp-1252' - with upper-range bytes escaped if
+ decoding with the fallback encoding also fails.
+ Under python2 the default strategy is 'passthrough' for historical
+ reasons, and under python3 the default is 'fallback'.
+ When 'strict' is selected and decoding fails, the error message will
+ propose changing this config parameter as a workaround. If this
+ option is passed into a p4 clone request, it is persisted into the
+ resulting new git repo.
+
+git-p4.metadataFallbackEncoding::
+ Specify the fallback encoding to use when decoding Perforce author
+ names and changelists descriptions using the 'fallback' strategy
+ (see git-p4.metadataDecodingStrategy). The fallback encoding will
+ only be used when decoding as utf-8 fails. This option defaults to
+ cp1252, a common windows encoding. If this option is passed into a
+ p4 clone request, it is persisted into the resulting new git repo.
+
+git-p4.largeFileSystem::
+ Specify the system that is used for large (binary) files. Please note
+ that large file systems do not support the 'git p4 submit' command.
+ Only Git LFS is implemented right now (see https://git-lfs.github.com/
+ for more information). Download and install the Git LFS command line
+ extension to use this option and configure it like this:
++
+-------------
+git config git-p4.largeFileSystem GitLFS
+-------------
+
+git-p4.largeFileExtensions::
+ All files matching a file extension in the list will be processed
+ by the large file system. Do not prefix the extensions with '.'.
+
+git-p4.largeFileThreshold::
+ All files with an uncompressed size exceeding the threshold will be
+ processed by the large file system. By default the threshold is
+ defined in bytes. Add the suffix k, m, or g to change the unit.
+
+git-p4.largeFileCompressedThreshold::
+ All files with a compressed size exceeding the threshold will be
+ processed by the large file system. This option might slow down
+ your clone/sync process. By default the threshold is defined in
+ bytes. Add the suffix k, m, or g to change the unit.
+
+git-p4.largeFilePush::
+ Boolean variable which defines if large files are automatically
+ pushed to a server.
+
+git-p4.keepEmptyCommits::
+ A changelist that contains only excluded files will be imported
+ as an empty commit if this boolean option is set to true.
+
+git-p4.mapUser::
+ Map a P4 user to a name and email address in Git. Use a string
+ with the following format to create a mapping:
++
+-------------
+git config --add git-p4.mapUser "p4user = First Last <mail@address.com>"
+-------------
++
+A mapping will override any user information from P4. Mappings for
+multiple P4 user can be defined.
+
+Submit variables
+~~~~~~~~~~~~~~~~
+git-p4.detectRenames::
+ Detect renames. See linkgit:git-diff[1]. This can be true,
+ false, or a score as expected by 'git diff -M'.
+
+git-p4.detectCopies::
+ Detect copies. See linkgit:git-diff[1]. This can be true,
+ false, or a score as expected by 'git diff -C'.
+
+git-p4.detectCopiesHarder::
+ Detect copies harder. See linkgit:git-diff[1]. A boolean.
+
+git-p4.preserveUser::
+ On submit, re-author changes to reflect the Git author,
+ regardless of who invokes 'git p4 submit'.
+
+git-p4.allowMissingP4Users::
+ When 'preserveUser' is true, 'git p4' normally dies if it
+ cannot find an author in the p4 user map. This setting
+ submits the change regardless.
+
+git-p4.skipSubmitEdit::
+ The submit process invokes the editor before each p4 change
+ is submitted. If this setting is true, though, the editing
+ step is skipped.
+
+git-p4.skipSubmitEditCheck::
+ After editing the p4 change message, 'git p4' makes sure that
+ the description really was changed by looking at the file
+ modification time. This option disables that test.
+
+git-p4.allowSubmit::
+ By default, any branch can be used as the source for a 'git p4
+ submit' operation. This configuration variable, if set, permits only
+ the named branches to be used as submit sources. Branch names
+ must be the short names (no "refs/heads/"), and should be
+ separated by commas (","), with no spaces.
+
+git-p4.skipUserNameCheck::
+ If the user running 'git p4 submit' does not exist in the p4
+ user map, 'git p4' exits. This option can be used to force
+ submission regardless.
+
+git-p4.attemptRCSCleanup::
+ If enabled, 'git p4 submit' will attempt to cleanup RCS keywords
+ ($Header$, etc). These would otherwise cause merge conflicts and prevent
+ the submit going ahead. This option should be considered experimental at
+ present.
+
+git-p4.exportLabels::
+ Export Git tags to p4 labels, as per --export-labels.
+
+git-p4.labelExportRegexp::
+ Only p4 labels matching this regular expression will be exported. The
+ default value is '[a-zA-Z0-9_\-.]+$'.
+
+git-p4.conflict::
+ Specify submit behavior when a conflict with p4 is found, as per
+ --conflict. The default behavior is 'ask'.
+
+git-p4.disableRebase::
+ Do not rebase the tree against p4/master following a submit.
+
+git-p4.disableP4Sync::
+ Do not sync p4/master with Perforce following a submit. Implies git-p4.disableRebase.
+
+IMPLEMENTATION DETAILS
+----------------------
+* Changesets from p4 are imported using Git fast-import.
+* Cloning or syncing does not require a p4 client; file contents are
+ collected using 'p4 print'.
+* Submitting requires a p4 client, which is not in the same location
+ as the Git repository. Patches are applied, one at a time, to
+ this p4 client and submitted from there.
+* Each commit imported by 'git p4' has a line at the end of the log
+ message indicating the p4 depot location and change number. This
+ line is used by later 'git p4 sync' operations to know which p4
+ changes are new.
