"""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".

This command accepts an optional name of a shelved change to
restore. If none is given, the most recent shelved change is used.
If a shelved change is applied successfully, the bundle that
contains the shelved changes is moved to a backup location
(.hg/shelve-backup).
Since you can restore a shelved change on top of an arbitrary
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.)
If bare shelved change(when no files are specified, without interactive,
include and exclude option) was done on newly created branch it would
restore branch information to the working directory.
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
prevents from deciding exact order of them, for safety.

'''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.
In bare shelve(when no files are specified, without interactive,
include and exclude option), shelving remembers information if the
working directory was on newly created branch, in other words working
directory was on different branch than its first parent. In this
situation unshelving restores branch information to the working directory.
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``.
