'''patch management and development
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):
prepare repository to work with patches qinit
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
print name of top applied patch qtop
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh

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.'''
