 '''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
