mq allows you to maintain changesets as patches.  They can be applied or 
removed, reordered, deleted etc.  This is one workload where it can help, 
basically making it easy to use hg but still create finalized versions of 
your changesets in patch form.

If you aren't already familiar with quilt (which mq is modeled after), it's 
probably easiest to follow the example command by command, and look a the 
state of the repository and the contents of .hg/patches after each command.

If you just want a quick and dirty mechanism to consolidate patches, something 
like this will work with the mq extension:

# export all of your changesets as one patch
hg export rev1 rev2 ... > patchfile

# edit the patch file to change the comments
# remove all # HG changeset patch blocks other than the first one.
vi patchfile

# remove all the revisions you just exported.  This will also remove all
# revisions after rev1 from the tree, use with great care.
hg strip rev1

# import the patch
hg import < patchfile
