63 \\fICVS-REPOS-PATH\\fR is the filesystem path of the part of the CVS
64 repository that you want to convert. This path doesn't have to be the
65 top level directory of a CVS repository; it can point at a project
66 within a repository, in which case only that project will be
67 converted. This path or one of its parent directories has to contain

71 It is not possible directly to convert a CVS repository to which you
72 only have remote access, but the FAQ describes tools that may be used
