    This directory contains code which can directly read RCS ,v files and
    generate a git-style rev-list structure from them. Revision lists can be
    merged together to produce a composite revision history for an arbitrary
    collection of files.

    Optional behaviors are controlled by editing the source and recompiling.

    If arguments are supplied, `parsecvs` assumes they're all ,v files and reads
    them in. If no arguments are supplied, `parsecvs` reads filenames from stdin,
    one per line.

    Working features:

            Attic support. Files found in the Attic are not dealt with specially
            at all; they should be renamed in the output, and the terminal
            revision noted so that they don't appear in later revision. I think
            fixing this will be reasonably straightforward.

            Disjoint branch resolution. Branches occurring in a subset of the
            files are not correctly resolved; instead, an entirely disjoint
            history will be created containing the branch revisions and all
            parents back to the root. I'm not sure how to fix this; it seems
            to implicitly assume there will be only a single place to attach as
            branch parent, which may not be the case. In any case, the right
            revision will have a superset of the revisions present in the
            original branch parent; perhaps that will suffice.

            Connection to git. As mentioned above, the code doesn't actually
            connect to git yet, so while it can generate lovely graphs, it won't
            do anything useful. I think this is reasonably straight forward as
            well; we've got a revision history containing the necessary version
            of every file at each point in time. This could either be done by
            emitting git commands and sending them to a shell, or by linking
            against a git library and doing everything internally.

            Author translation. Just as git cvsimport does.


    Missing features:

            Reasonable command line syntax. The current lack of command line
            parsing should be fixed to align with the usual git tools.

            Testing. I'm sure there are plenty of additional bugs to be found;
            I've tested with valgrind and eliminated memory leaks and other
            errors.
