convert: checkout svn root revisions
Using changed files is enough if whole history is converted. Checkouts are
required to restrict the conversion to user-supplied subtree.

% help 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 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 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 use "hg -v help mq" to show aliases and global options adding a 1 files updated, 0 files merged, 0 files removed, 0 files unresolved adding b/z % qinit % -R qinit % qinit -c A .hgignore A series % qnew implies add A .hgignore A series A test.patch % qinit;
