   $ hg help mq
   mq extension - 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 behavior 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.
   
   It may be desirable for mq changesets to be kept in the secret phase (see 'hg
   help phases'), which can be enabled with the following setting:
   
     [mq]
     secret = True
   
   You will by default be managing a patch queue named "patches". You can create
   other, independent patch queues with the 'hg qqueue' command.
   
   If the working directory contains uncommitted files, qpush, qpop and qgoto
   abort immediately. If -f/--force is used, the changes are discarded. Setting:
   
     [mq]
     keepchanges = True
   
   make them behave as if --keep-changes were passed, and non-conflicting local
   changes will be tolerated and preserved. If incompatible options such as
   -f/--force or --exact are passed, this setting is ignored.
   
   This extension used to provide a strip command. This command now lives in the
   strip extension.
   
   list of commands:
   
    qapplied      print the patches already applied
    qclone        clone main and patch repository at same time
    qdelete       remove patches from queue
    qdiff         diff of the current patch and subsequent modifications
    qfinish       move applied patches into repository history
    qfold         fold the named patches into the current patch
    qgoto         push or pop patches until named patch is at top of stack
    qguard        set or print guards for a patch
    qheader       print the header of the topmost or specified patch
    qimport       import a patch or existing changeset
    qnew          create a new patch
    qnext         print the name of the next pushable patch
    qpop          pop the current patch off the stack
    qprev         print the name of the preceding applied patch
    qpush         push the next patch onto the stack
    qqueue        manage multiple patch queues
    qrefresh      update the current patch
    qrename       rename a patch
    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
