 """save and restore changes to the working directory
 
 The "hg shelve" command saves changes made to the working directory
 and reverts those changes, resetting the working directory to a clean
 state.
 
 Later on, the "hg unshelve" command restores the changes saved by "hg
 shelve". Changes can be restored even after updating to a different
 parent, in which case Mercurial's merge machinery will resolve any
 conflicts if necessary.
 
 You can have more than one shelved change outstanding at a time; each
 shelved change has a distinct name. For details, see the help for "hg
 shelve".

     If a shelved change is applied successfully, the bundle that
     contains the shelved changes is moved to a backup location

     commit, it is possible that unshelving will result in a conflict
     between your changes and the commits you are unshelving onto. If
     this occurs, you must resolve the conflict, then use
     ``--continue`` to complete the unshelve operation. (The bundle
     will not be moved until you successfully complete the unshelve.)
 
     (Alternatively, you can use ``--abort`` to abandon an unshelve
     that causes a conflict. This reverts the unshelved changes, and
     leaves the bundle in place.)
 
     After a successful unshelve, the shelved changes are stored in a
     backup directory. Only the N most recent backups are kept. N
     defaults to 10 but can be overridden using the ``shelve.maxbackups``
     configuration option.
 
     .. container:: verbose
 
        Timestamp in seconds is used to decide order of backups. More
        than ``maxbackups`` backups are kept, if same timestamp

     Shelving takes files that "hg status" reports as not clean, saves
     the modifications to a bundle (a shelved change), and reverts the
     files so that their state in the working directory becomes clean.
 
     To restore these changes to the working directory, using "hg
     unshelve"; this will work even if you switch to a different
     commit.
 
     When no files are specified, "hg shelve" saves all not-clean
     files. If specific files or directories are named, only changes to
     those files are shelved.
 
     Each shelved change has a name that makes it easier to find later.
     The name of a shelved change defaults to being based on the active
     bookmark, or if there is no active bookmark, the current named
     branch.  To specify a different name, use ``--name``.
 
     To see a list of existing shelved changes, use the ``--list``
     option. For each shelved change, this will print its name, age,
     and description; use ``--patch`` or ``--stat`` for more details.
 
     To delete specific shelved changes, use ``--delete``. To delete
     all shelved changes, use ``--cleanup``.

   save and set aside changes from the working directory
   
       Shelving takes files that "hg status" reports as not clean, saves the
       modifications to a bundle (a shelved change), and reverts the files so
       that their state in the working directory becomes clean.
   
       To restore these changes to the working directory, using "hg unshelve";
       this will work even if you switch to a different commit.
   
       When no files are specified, "hg shelve" saves all not-clean files. If
       specific files or directories are named, only changes to those files are
       shelved.
   
       Each shelved change has a name that makes it easier to find later. The
       name of a shelved change defaults to being based on the active bookmark,
       or if there is no active bookmark, the current named branch.  To specify a
       different name, use "--name".
   
       To see a list of existing shelved changes, use the "--list" option. For
       each shelved change, this will print its name, age, and description; use "
       --patch" or "--stat" for more details.
   
       To delete specific shelved changes, use "--delete". To delete all shelved
       changes, use "--cleanup".
   
   (use "hg help -e shelve" to show help for the shelve extension)
   
   options ([+] can be repeated):
   
    -A --addremove           mark new/missing files as added/removed before
                             shelving
    -u --unknown             store unknown files in the shelve
       --cleanup             delete all shelved changes
       --date DATE           shelve with the specified commit date
    -d --delete              delete the named shelved change(s)
    -e --edit                invoke editor on commit messages
    -l --list                list current shelves
    -m --message TEXT        use text as shelve message
    -n --name NAME           use the given name for the shelved commit
    -p --patch               show patch
    -i --interactive         interactive mode, only works while creating a shelve
       --stat                output diffstat-style summary of changes
    -I --include PATTERN [+] include names matching the given patterns
    -X --exclude PATTERN [+] exclude names matching the given patterns
       --mq                  operate on patch repository
   
   (some details hidden, use --verbose to show complete help)

 (1) commit changes in the working directory (REV6)
 (2) unbundle shelved revision (REV7)
 (3) rebase: merge REV7 into REV6 (REV6 => REV6, REV7)
 (4) rebase: commit merged revision (REV8)
 (5) rebase: update to REV6 (REV8 => REV6)
 (6) update to REV5 (REV6 => REV5)
 (7) abort transaction

 Shelve and unshelve unknown files. For the purposes of unshelve, a shelved
 unknown file is the same as a shelved added file, except that it will be in
 unknown state after unshelve if and only if it was either absent or unknown
 before the unshelve operation.
 
   $ hg init unknowns
   $ cd unknowns
 
 The simplest case is if I simply have an unknown file that I shelve and unshelve
 
   $ echo unknown > unknown
   $ hg status
   ? unknown
   $ hg shelve --unknown
   shelved as default
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg status
   $ hg unshelve
   unshelving change 'default'
   $ hg status
   ? unknown
   $ rm unknown
 
 If I shelve, add the file, and unshelve, does it stay added?
 
   $ echo unknown > unknown
   $ hg shelve -u
   shelved as default
   0 files updated, 0 files merged, 1 files removed, 0 files unresolved
   $ hg status
   $ touch unknown
