42 Create a new Mercurial repository based on the version history stored in
43 a CVS repository. Each CVS commit will be mirrored in the Mercurial
44 repository, including commit time and author (with optional remapping to
45 Mercurial-style long usernames).
47 \\fICVS-REPOS-PATH\\fR is the filesystem path of the part of the CVS
48 repository that you want to convert. It is not possible to convert a
49 CVS repository to which you only have remote access; see the FAQ for
50 more information. This path doesn't have to be the top level
51 directory of a CVS repository; it can point at a project within a
52 repository, in which case only that project will be converted. This
53 path or one of its parent directories has to contain a subdirectory
54 called CVSROOT (though the CVSROOT directory can be empty). If
55 omitted, the repository path defaults to the current directory.
57 Unlike CVS or Subversion, Mercurial expects each repository to hold
58 one independent project. If your CVS repository contains multiple
59 independent projects, you should probably convert them to multiple
60 independent Mercurial repositories with multiple runs of
