Migrate project from RCS to git?

See InterfacesFrontendsAndTools page on Git Wiki, in "Tools", "Interaction with other Revision Control Systems", "Other". There you would find a description and a link to rcs-fast-export (gitweb) Ruby script by Giuseppe "Oblomov" Bilotta.

(Web search would find also Ohloh page and announcement for mentioned project).

OK, after a little tinkering, I found it was trivial to convert RCS to CVS. The files are in the same format, so it's simply a matter of moving the files into an existing CVS root. This assumes you have access to the RCS files.

# Create CVS root dir. You only need to do this once.mkdir $HOME/cvs/cd $HOME/cvs/cvs init# Import a repository from RCS to CVScp -a _projectname_/RCS $HOME/cvs/_projectname_

As a general rule you should be careful as to what scripts you run. For RCS -> GIT it may be in your best interest to follow the RCS->CVS->GIT methodology.

Took a quick look at rcs-fast-export.rb as of 2011-01-12 and ran across this portion of the code. This is scary at best.
