 NAME
 ----
 hg - Mercurial source code management system
 
 SYNOPSIS
 --------
 'hg' [-v -d -q -y] <command> [command options] [files]
 
 DESCRIPTION
 -----------
 The hg(1) command provides a command line interface to the Mercurial system.
 
 OPTIONS
 -------
 
 --debug, -d::
     enable debugging output
 
 --quiet, -q::
     suppress output
 
 --verbose, -v::
     enable additional output
 
 --noninteractive, -y::
     do not prompt, assume 'yes' for any required answers
 
 COMMAND ELEMENTS
 ----------------
 
 files ...::
     indicates one or more filename or relative path filenames; see
     "FILE NAME PATTERNS" for information on pattern matching
 
 path::
     indicates a path on the local machine
 
 revision::
     indicates a changeset which can be specified as a changeset revision
     number, a tag, or a unique substring of the changeset hash value
 
 repository path::
     either the pathname of a local repository or the URI of a remote
     repository.  There are two available URI protocols, http:// which is
     fast and the old-http:// protocol which is much slower but does not
     require a special server on the web host.
 
 COMMANDS
 --------
 
 add [options] [files ...]::
     Schedule files to be version controlled and added to the repository.
     
     The files will be added to the repository at the next commit.
 
     If no names are given, add all files in the current directory and
     its subdirectories.
 
 addremove [options] [files ...]::
     Add all new files and remove all missing files from the repository.
     
     New files are ignored if they match any of the patterns in .hgignore. As
     with add, these changes take effect at the next commit.
 
 annotate [-r <rev> -u -n -c] [files ...]::
     List changes in files, showing the revision id responsible for each line
     
     This command is useful to discover who did a change or when a change took
     place.
     
     options:
     -I, --include <pat>   include names matching the given patterns
     -X, --exclude <pat>   exclude names matching the given patterns
     -r, --revision <rev>  annotate the specified revision
     -u, --user            list the author
     -c, --changeset       list the changeset
     -n, --number          list the revision number (default)
 
 cat <file> [revision]::
     Output to stdout the given revision for the specified file.
 
     If no revision is given then the tip is used.
 
 clone [-U] <source> [dest]::
     Create a copy of an existing repository in a new directory.
 
     If no destination directory name is specified, it defaults to the
     basename of the source.
 
     The source is added to the new repository's .hg/hgrc file to be used in
     future pulls.
 
     For efficiency, hardlinks are used for cloning whenever the
     source and destination are on the same filesystem.
 
     options:
     -U, --noupdate   do not update the new working directory
 
 commit [options] [files...]::
     Commit changes to the given files into the repository.
     
     If a list of files is omitted, all changes reported by "hg status"
     from the root of the repository will be commited.
     
     The HGEDITOR or EDITOR environment variables are used to start an
     editor to add a commit comment.
 
     Options:
 
     -A, --addremove       run addremove during commit
     -I, --include <pat>   include names matching the given patterns
     -X, --exclude <pat>   exclude names matching the given patterns
     -m, --message <text>  use <text> as commit message
     -l, --logfile <file>  show the commit message for the given file
     -d, --date <datecode> record datecode as commit date
     -u, --user <user>     record user as commiter
 
     aliases: ci
 
 copy <source> <dest>::
     Mark <dest> file as a copy or rename of a <source> one
     
     This command takes effect for the next commit.
 
 diff [-r revision] [-r revision] [files ...]::
     Show differences between revisions for the specified files.
     
     Differences between files are shown using the unified diff format.
     
     When two revision arguments are given, then changes are shown
     between those revisions. If only one revision is specified then
     that revision is compared to the working directory, and, when no
     revisions are specified, the working directory files are compared
     to its parent.
 
     options:
     -I, --include <pat>  include names matching the given patterns
     -X, --exclude <pat>  exclude names matching the given patterns
 
 export [-o filespec] [revision] ...::
     Print the changeset header and diffs for one or more revisions.
 
     The information shown in the changeset header is: author,
     changeset hash, parent and commit comment.
 
     Output may be to a file, in which case the name of the file is
     given using a format string.  The formatting rules are as follows:
 
     %%   literal "%" character
     %H   changeset hash (40 bytes of hexadecimal)
     %N   number of patches being generated
     %R   changeset revision number
     %b   basename of the exporting repository
     %h   short-form changeset hash (12 bytes of hexadecimal)
     %n   zero-padded sequence number, starting at 1
     %r   zero-padded changeset revision number
 
     Options:
 
     -o, --output <filespec>   print output to file with formatted named
 
 forget [options] [files]::
     Undo an 'hg add' scheduled for the next commit.
 
     options:
     -I, --include <pat>  include names matching the given patterns
     -X, --exclude <pat>  exclude names matching the given patterns
 
 heads::
     Show all repository head changesets.
     
     Repository "heads" are changesets that don't have children
     changesets. They are where development generally takes place and
     are the usual targets for update and merge operations.
 
 identify::
     Print a short summary of the current state of the repo.
     
     This summary identifies the repository state using one or two parent
     hash identifiers, followed by a "+" if there are uncommitted changes
     in the working directory, followed by a list of tags for this revision.
 
     aliases: id
 
 import [-p <n> -b <base> -q] <patches>::
     Import a list of patches and commit them individually.
 
     options:
     -p, --strip <n>   directory strip option for patch. This has the same
                       meaning as the correnponding patch option
     -b <path>         base directory to read patches from
 
     aliases: patch
 
 init::
     Initialize a new repository in the current directory.
 
 locate [options] [files]::
     Print all files under Mercurial control whose names match the
     given patterns.
 
     This command searches the current directory and its
     subdirectories.  To search an entire repository, move to the root
     of the repository.
 
     If no patterns are given to match, this command prints all file
     names.
 
     If you want to feed the output of this command into the "xargs"
     command, use the "-0" option to both this command and "xargs".
     This will avoid the problem of "xargs" treating single filenames
     that contain white space as multiple file names.
 
     options:
 
     -0, --print0         end filenames with NUL, for use with xargs
     -f, --fullpath       print complete paths from the filesystem root
     -I, --include <pat>  include names matching the given patterns
     -r, --rev <rev>      search the repository as it stood at rev
     -X, --exclude <pat>  exclude names matching the given patterns
 
 log [-r revision ...] [-p] [file]::
     Print the revision history of the specified file or the entire project.
 
     By default this command outputs: changeset id and hash, tags,
     parents, user, date and time, and a summary for each commit. The
     -v switch adds some more detail, such as changed files, manifest
     hashes or message signatures.
 
     options:
     -r, --rev <A>, ...  When a revision argument is given, only this file or
                         changelog revision is displayed. With two revision
                         arguments all revisions in this range are listed.
                         Additional revision arguments may be given repeating
                         the above cycle.
     -p, --patch         show patch
 
     aliases: history
 
 manifest [revision]::
     Print a list of version controlled files for the given revision.
 
     The manifest is the list of files being version controlled. If no revision
     is given then the tip is used.
 
 parents::
     Print the working directory's parent revisions.
 
 pull <repository path>::
     Pull changes from a remote repository to a local one.
 
     This finds all changes from the repository at the specified path
     or URL and adds them to the local repository. By default, this
     does not update the copy of the project in the working directory.
 
     options:
     -u, --update   update the working directory to tip after pull
 
 push <destination>::
     Push changes from the local repository to the given destination.
     
     This is the symmetrical operation for pull. It helps to move
     changes from the current repository to a different one. If the
     destination is local this is identical to a pull in that directory
     from the current one.
 
     The other currently available push method is SSH. This requires an
     accessible shell account on the destination machine and a copy of
     hg in the remote path. Destinations are specified in the following
     form:
 
       ssh://[user@]host[:port]/path
 
 rawcommit [-p -d -u -F -m -l]::
     Lowlevel commit, for use in helper scripts.
     
     This command is not intended to be used by normal users, as it is
     primarily useful for importing from other SCMs.
 
 recover::
     Recover from an interrupted commit or pull.
     
     This command tries to fix the repository status after an interrupted
     operation. It should only be necessary when Mercurial suggests it.
 
 remove [files ...]::
     Schedule the indicated files for removal from the repository.
     
     This command shedules the files to be removed at the next commit.
     This only removes files from the current branch, not from the
     entire project history.
 
     aliases: rm
 
 revert [names ...]::
     Revert any uncommitted modifications made to the named files or
     directories.  This restores the contents of the affected files to
     an unmodified state.
 
     If a file has been deleted, it is recreated.  If the executable
     mode of a file was changed, it is reset.
 
     If a directory is given, all files in that directory and its
     subdirectories are reverted.
 
     If no arguments are given, all files in the current directory and
     its subdirectories are reverted.
 
     options:
     -r, --rev <rev>       revision to revert to
     -n, --nonrecursive    do not recurse into subdirectories
 
 root::
     Print the root directory of the current repository.
 
 serve [options]::
     Start a local HTTP repository browser and pull server.
 
     By default, the server logs accesses to stdout and errors to
     stderr.  Use the "-A" and "-E" options to log to files.
 
     options:
     -A, --accesslog <file>   name of access log file to write to
     -E, --errorlog <file>    name of error log file to write to
     -a, --address <addr>     address to use
     -p, --port <n>           port to use (default: 8000)
     -n, --name <name>        name to show in web pages (default: working dir)
     -t, --templatedir <path> web templates to use
+    -6, --ipv6               use IPv6 in addition to IPv4
 
 status [options] [files]::
     Show changed files in the working directory.  If no names are
     given, all files are shown.  Otherwise, only files matching the
     given names are shown.
 
     The codes used to show the status of files are:
     
     M = changed
     A = added
     R = removed
     ? = not tracked
 
     options:
 
     -I, --include <pat>  include names matching the given patterns
     -X, --exclude <pat>  exclude names matching the given patterns
 
 tag [-l -m <text> -d <datecode> -u <user>] <name> [revision]::
     Name a particular revision using <name>.
     
     Tags are used to name particular revisions of the repository and are
     very useful to compare different revision, to go back to significant
     earlier versions or to mark branch points as releases, etc.
     
     If no revision is given, the tip is used.
 
     To facilitate version control, distribution, and merging of tags,
     they are stored as a file named ".hgtags" which is managed
     similarly to other project files and can be hand-edited if
     necessary.
 
     options:
     -l, --local           make the tag local
     -m, --message <text>  message for tag commit log entry
     -d, --date <datecode> datecode for commit
     -u, --user <user>     user for commit
 
     Note: Local tags are not version-controlled or distributed and are
     stored in the .hg/localtags file. If there exists a local tag and
     a public tag with the same name, local tag is used.
 
 tags::
     List the repository tags.
 
     This lists both regular and local tags.
 
 tip::
     Show the tip revision.
 
 undo::
     Undo the last commit or pull transaction.
 
     Roll back the last pull or commit transaction on the
     repository, restoring the project to its earlier state.
 
     This command should be used with care. There is only one level of
     undo and there is no redo.
 
     This command is not intended for use on public repositories. Once
     a change is visible for pull by other users, undoing it locally is
     ineffective.
 
 update [-m -C] [revision]::
     Update the working directory to the specified revision.
 
     By default, update will refuse to run if doing so would require
     merging or discarding local changes.
 
     With the -m option, a merge will be performed.
 
     With the -C option, local changes will be lost.
     
     options:
     -m, --merge       allow merging of branches
     -C, --clean       overwrite locally modified files
 
     aliases: up checkout co
 
 verify::
     Verify the integrity of the current repository.
 
     This will perform an extensive check of the repository's
     integrity, validating the hashes and checksums of each entry in
     the changelog, manifest, and tracked files, as well as the
     integrity of their crosslinks and indices.
 
 FILE NAME PATTERNS
 ------------------
 
     Mercurial accepts several notations for identifying one or more
     file at a time.
 
     By default, Mercurial treats file names as shell-style extended
     glob patterns.
 
     Alternate pattern notations must be specified explicitly.
 
     To use a plain path name without any pattern matching, start a
     name with "path:".  These path names must match completely, from
     the root of the current repository.
 
     To use an extended glob, start a name with "glob:".  Globs are
     rooted at the current directory; a glob such as "*.c" will match
     files ending in ".c" in the current directory only.
 
     The supported glob syntax extensions are "**" to match any string
     across path separators, and "{a,b}" to mean "a or b".
 
     To use a Perl/Python regular expression, start a name with "re:".
     Regexp pattern matching is anchored at the root of the repository.
 
     Plain examples:
 
     path:foo/bar   a name bar in a directory named foo in the root of
                    the repository
     path:path:name a file or directory named "path:name"
 
     Glob examples:
 
     glob:*.c       any name ending in ".c" in the current directory
     *.c            any name ending in ".c" in the current directory
     **.c           any name ending in ".c" in the current directory, or
                    any subdirectory
     foo/*.c        any name ending in ".c" in the directory foo
     foo/**.c       any name ending in ".c" in the directory foo, or any
                    subdirectory
 
     Regexp examples:
 
     re:.*\.c$      any name ending in ".c", anywhere in the repsitory
 
 
 SPECIFYING SINGLE REVISIONS
 ---------------------------
 
     Mercurial accepts several notations for identifying individual
     revisions.
 
     A plain integer is treated as a revision number.  Negative
     integers are treated as offsets from the tip, with -1 denoting the
     tip.
 
     A 40-digit hexadecimal string is treated as a unique revision
     identifier.
 
     A hexadecimal string less than 40 characters long is treated as a
     unique revision identifier, and referred to as a short-form
     identifier.  A short-form identifier is only valid if it is the
     prefix of one full-length identifier.
 
     Any other string is treated as a tag name, which is a symbolic
     name associated with a revision identifier.  Tag names may not
     contain the ":" character.
 
     The reserved name "tip" is a special tag that always identifies
     the most recent revision.
 
 SPECIFYING MULTIPLE REVISIONS
 -----------------------------
 
     When Mercurial accepts more than one revision, they may be
     specified individually, or provided as a continuous range,
     separated by the ":" character.
 
     The syntax of range notation is [BEGIN]:[END], where BEGIN and END
     are revision identifiers.  Both BEGIN and END are optional.  If
     BEGIN is not specified, it defaults to revision number 0.  If END
     is not specified, it defaults to the tip.  The range ":" thus
     means "all revisions".
 
     If BEGIN is greater than END, revisions are treated in reverse
     order.
 
     A range acts as an open interval.  This means that a range of 3:5
     gives 3, 4 and 5.  Similarly, a range of 4:2 gives 4, 3, and 2.
 
 ENVIRONMENT VARIABLES
 ---------------------
 
 HGEDITOR::
     This is the name of the editor to use when committing. Defaults to the
     value of EDITOR. 
 
     (deprecated, use .hgrc)
 
 HGMERGE::
     An executable to use for resolving merge conflicts. The program
     will be executed with three arguments: local file, remote file,
     ancestor file.
 
     The default program is "hgmerge", which is a shell script provided
     by Mercurial with some sensible defaults.
 
     (deprecated, use .hgrc)
 
 HGUSER::
     This is the string used for the author of a commit.
 
     (deprecated, use .hgrc)
 
 EMAIL::
     If HGUSER is not set, this will be used as the author for a commit.
 
 LOGNAME::
     If neither HGUSER nor EMAIL is set, LOGNAME will be used (with
     '@hostname' appended) as the author value for a commit.
 
 EDITOR::
     This is the name of the editor used in the hgmerge script. It will be
     used for commit messages if HGEDITOR isn't set. Defaults to 'vi'.
 
 PYTHONPATH::
     This is used by Python to find imported modules and may need to be set
     appropriately if Mercurial is not installed system-wide.
 
 FILES
 -----
  .hgignore::
     This file contains regular expressions (one per line) that describe file
     names that should be ignored by hg.
 
  .hgtags::
     This file contains changeset hash values and text tag names (one of each
     seperated by spaces) that correspond to tagged versions of the repository
     contents.
 
  $HOME/.hgrc, .hg/hgrc::
     This file contains defaults and configuration. Values in .hg/hgrc
     override those in .hgrc.  See hgrc(5) for details of the contents
     and format of these files.
 
 BUGS
 ----
 Probably lots, please post them to the mailing list (See Resources below)
 when you find them.
