     The location of the source is added to the new repository's
     .hg/hgrc file, as the default to be used for future pulls.
 
     For efficiency, hardlinks are used for cloning whenever the source
     and destination are on the same filesystem (note this applies only
     to the repository data, not to the checked out files).  Some
     filesystems, such as AFS, implement hardlinking incorrectly, but
     do not report errors.  In these cases, use the --pull option to

     atomic (making sure REPO is not modified during the operation is
     up to you) and you have to make sure your editor breaks hardlinks
     (Emacs and most Linux Kernel tools do so).
 
     If you use the -r option to clone up to a specific revision, no
     subsequent revisions will be present in the cloned repository.
     This option implies --pull, even on local repositories.
 
     See pull for valid source format details.
 
     It is possible to specify an ssh:// URL as the destination, but no

     - SSH requires an accessible shell account on the destination machine

     - path is relative to the remote user's home directory by default.
       Use an extra slash at the start of a path to specify an absolute path:
         ssh://example.com//tmp/repository
     - Mercurial doesn't use its own compression via SSH; the right thing
       to do is to configure it in your ~/.ssh/config, e.g.:
         Host *.mylocalnetwork.example.com
           Compression no
         Host *
           Compression yes
       Alternatively specify "ssh -C" as your ssh command in your hgrc or

     state.  If the working directory has two parents, you must

     Roll back the last transaction in this repository, restoring the

     Transactions are used to encapsulate the effects of all commands

     and their effects can be rolled back:

     This command should be used with care. There is only one level of
     rollback, and there is no way to undo a rollback.
 
     This command is not intended for use on public repositories. Once
     changes are visible for pull by other users, rolling a transaction
     back locally is ineffective (someone else may already have pulled
     the changes). Furthermore, a race is possible with readers of the

     r'''
     Some commands (backout, commit, tag) allow the user to specify a date.
-    Possible formats for dates are:
-
-YYYY-mm-dd \HH:MM[:SS] [(+|-)NNNN]::
-    This is a subset of ISO 8601, allowing just the recommended notations
-    for date and time. The last part represents the timezone; if omitted,
-    local time is assumed. Examples:
-
-    "2005-08-22 03:27 -0700"
-
-    "2006-04-19 21:39:51"
+    Many date formats are acceptible. Here are some examples:
 
-aaa bbb dd HH:MM:SS YYYY [(+|-)NNNN]::
-    This is the date format used by the C library. Here, aaa stands for
-    abbreviated weekday name and bbb for abbreviated month name. The last
-    part represents the timezone; if omitted, local time is assumed.
-    Examples:
+    "Wed Dec 6 13:18:29 2006" (local timezone assumed)
+    "Dec 6 13:18 -0600" (year assumed, time offset provided)
+    "Dec 6 13:18 UTC" (UTC and GMT are aliases for +0000)
+    "Dec 6" (midnight)
+    "13:18" (today assumed)
+    "3:39" (3:39AM assumed)
+    "3:39pm" (15:39)
+    "2006-12-6 13:18:29" (ISO 8601 format)
+    "2006-12-6 13:18"
+    "2006-12-6"
+    "12-6"
+    "12/6"
+    "12/6/6" (Dec 6 2006)
+    "" (Jan 1 00:00:00 1970 UTC)
 
-    "Mon Aug 22 03:27:00 2005 -0700"
+    Lastly, there is Mercurial's internal format:
 
-    "Wed Apr 19 21:39:51 2006"
+    "1165432709 0" (Wed Dec 6 13:18:29 2006 UTC)
 
-unixtime offset::
     This is the internal representation format for dates. unixtime is
     the number of seconds since the epoch (1970-01-01 00:00 UTC). offset
     is the offset of the local timezone, in seconds west of UTC (negative
     if the timezone is east of UTC).
-    Examples:
-
-    "1124706420 25200" (2005-08-22 03:27:00 -0700)
-
-    "1145475591 -7200" (2006-04-19 21:39:51 +0200)

 HGEDITOR::
     This is the name of the editor to use when committing. Defaults to the
     value of EDITOR.
 
     (deprecated, use .hgrc)
 
 HGENCODING::
     This overrides the default locale setting detected by Mercurial.
     This setting is used to convert data including usernames,
     changeset descriptions, tag names, and branches. This setting can
     be overridden with the --encoding command-line option.
 
 HGENCODINGMODE::
     This sets Mercurial's behavior for handling unknown characters
     while transcoding user inputs. The default is "strict", which
     causes Mercurial to abort if it can't translate a character. Other
     settings include "replace", which replaces unknown characters, and
     "ignore", which drops them. This setting can be overridden with
     the --encodingmode command-line option.
 
 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)
 
 HGRCPATH::
     A list of files or directories to search for hgrc files.  Item
     separator is ":" on Unix, ";" on Windows.  If HGRCPATH is not set,
     platform default search path is used.  If empty, only .hg/hgrc of
     current repository is read.
 
     For each element in path, if a directory, all entries in directory
     ending with ".rc" are added to path.  Else, element itself is
     added to path.
 
 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.

     "patterns|File Name Patterns": r'''
     Mercurial accepts several notations for identifying one or more
     files at a time.
 
     By default, Mercurial treats filenames 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 repository
