'''manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial
repository. It manages two stacks of patches - all known patches, and
applied patches (subset of known patches).
Known patches are represented as patch files in the .hg/patches
directory. Applied patches are both patch files and changesets.
Common tasks (use :hg:`help command` for more details)::
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to
avoid losing file mode changes, copy records, binary files or empty
files creations or deletions. This behaviour can be configured with::
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while
preserving existing git patches upon qrefresh. If set to 'yes' or
'no', mq will override the [diff] section and always generate git or
regular patches, possibly losing data in the second case.
You will by default be managing a patch queue named "patches". You can
create other, independent patch queues with the :hg:`qqueue` command.

Use the :hg:`qguard` command to set or print guards on patch, then use
qselect to tell mq which guards to use. A patch will be pushed if
it has no guards or any positive guards match the currently
selected guard, but will not be pushed if any negative guards
match the current guard. For example::
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because
it has a negative match) but push bar.patch (because it has a
positive match).
With no arguments, prints the currently active guards.
With one argument, sets the active guard.
Use -n/--none to deactivate guards (no other arguments needed).
When no guards are active, patches with positive guards are
skipped and patches with negative guards are pushed.
qselect can change the guards on applied patches. It does not pop
guarded patches by default. Use --pop to pop back to the last
applied patch that is not guarded. Use --reapply (which implies
--pop) to push back to the current patch afterwards, but skip
guarded patches.
Use -s/--series to print a list of all guards in the series file
(no other arguments needed). Use -v for more information.
