LONG_USAGE="Import hg repository <repo> up to either tip or <max>
If <repo> is omitted, use last hg repository as obtained from state file,
GIT_DIR/$PFX-$SFX_STATE by default.
Note: The argument order matters.
Options:
-m Maximum revision to import
--quiet Passed to git-fast-import(1)
-s Enable parsing Signed-off-by lines
-A Read author map from file
(Same as in git-svnimport(1) and git-cvsimport(1))
-r Mercurial repository to import
-M Set the default branch name (default to 'master')
-o Use <name> as branch namespace to track upstream (eg 'origin')
--force Ignore validation errors when converting, and pass --force
to git-fast-import(1)
