32 LONG_USAGE="Import hg repository <repo> up to either tip or <max>
33 If <repo> is omitted, use last hg repository as obtained from state file,
34 GIT_DIR/$PFX-$SFX_STATE by default.
36 Note: The argument order matters.
38 Options:
39 --quiet Passed to git-fast-import(1)
40 -r <repo> Mercurial repository to import
41 --force Ignore validation errors when converting, and pass --force
42 to git-fast-import(1)
43 -m <max> Maximum revision to import
44 -s Enable parsing Signed-off-by lines
45 --hgtags Enable exporting .hgtags files
46 -A <file> Read author map from file
47 (Same as in git-svnimport(1) and git-cvsimport(1))
48 -B <file> Read branch map from file
49 -T <file> Read tags map from file
50 -M <name> Set the default branch name (defaults to 'master')
51 -o <name> Use <name> as branch namespace to track upstream (eg 'origin')
52 --hg-hash Annotate commits with the hg hash as git notes in the
53 hg namespace.
54 -e <encoding> Assume commit and author strings retrieved from
55 Mercurial are encoded in <encoding>
56 --fe <filename_encoding> Assume filenames from Mercurial are encoded
57 in <filename_encoding>
58 --mappings-are-raw Assume mappings are raw <key>=<value> lines
59 --filter-contents <cmd> Pipe contents of each exported file through <cmd>
60 with <file-path> <hg-hash> <is-binary> as arguments
