Unpack a git fast-import stream into an RCS file tree.

The metadata in modern DVCSes can't really be stuffed back into RCS, but this tool makes a valiant effort and may be useful for extracting the revision histories of individual files from a project history.

I wrote this as a prod at more recent and putatively more advanced version-control systems that don't have .fi importers yet. If crufty old RCS can import these streams, why can't yours?
