Mercurial > hgsubversion

annotate hgsubversion/svncommands.py @ 337:46e69be8e2c8

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Reorganize to have a more conventional module structure. This means that hgsubversion now uses absolute imports instead of relative ones, which makes the tests more reliable.
