Export an RCS or CVS history as a fast-import stream


cvs-fast-export, formerly "parsecvs", does what its new name implies: exports CVS repositories in a format suitable for git fast-import.

This program analyzes a collection of RCS files in a CVS repository (or outside of one) and, when possible, emits an equivalent history in the form of a fast-import stream. Not all possible histories can be rendered this way; the program tries to emit useful warnings when it can't. The program can also produce a visualization of the resulting commit DAG in the DOT format handled by the graphviz suite.

The distribution includes a tool, cvssync, for fetching masters from CVS remote repositories so cvs-fast-export can see them. You will need rsync installed to use it.

A wrapper script called cvsconvert runs a conversion to git and looks for content mismatches with the original CVS. You will need CVS and Git installed to use it.

Also included is a tool called cvsstrip that strips content out of trees of RCS/CVS masters, leaving only metadata structure in place.
