mq extension - 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

list of commands:

 qapplied     print the patches already applied

 qclone       clone main and patch repository at same time

 qcommit      commit changes in the queue repository

 qdelete      remove patches from queue

 qdiff        diff of the current patch

 qfold        fold the named patches into the current patch

 qguard       set or print guards for a patch

 qheader      Print the header of the topmost or specified patch

 qimport      import a patch

 qinit        init a new queue repository

 qnew         create a new patch

 qnext        print the name of the next patch

 qpop         pop the current patch off the stack

 qprev        print the name of the previous patch

 qpush        push the next patch onto the stack

 qrefresh     update the current patch

 qrename      rename a patch

 qrestore     restore the queue state saved by a rev

 qsave        save current queue state

 qselect      set or print guarded patches to push

 qseries      print the entire series file

 qtop         print the name of the current patch

 qunapplied   print the patches not yet applied

 strip        strip a revision and all later revs on the same branch
