17 LONG_USAGE
="Import hg repository <repo> up to either tip or <max>
18 If <repo> is omitted, use last hg repository as obtained from state file,
19 GIT_DIR/$PFX-$SFX_STATE by default.
21 Note: The argument order matters.
24 --quiet Passed to git-fast-import(1)
25 -r <repo> Mercurial repository to import
26 --force Ignore validation errors when converting, and pass --force
28 -m <max> Maximum revision to import
29 -s Enable parsing Signed-off-by lines
30 --hgtags Enable exporting .hgtags files
31 -A <file> Read author map from file
32 (Same as in git-svnimport(1) and git-cvsimport(1))
33 -B <file> Read branch map from file
34 -T <file> Read tags map from file
35 -M <name> Set the default branch name (defaults to 'master')
36 -o <name> Use <name> as branch namespace to track upstream (eg 'origin')
