prcs2hg
Command to convert a PRCS project to Mercurial revisions
prcs2hg is a command (and also a Python package) to convert a PRCS project to Mercurial revisions. It would help you publish the revision history of an obsolete project whose changes were maintained with PRCS.
prcs2hg requires a working prcs command to extract versions from a PRCS repository and this project also provides the restored 'k' versions of PRCS for use with prcs2hg.
The source code repository is separately hosted on Bitbucket with a public issue tracker.
