RSCM - Ruby Source Control Management is to SCM what DBI/JDBC/ODBC are to databases - an SCM-independent API for accessing a wide variety of SCMs. RSCM currently supports CVS and Subversion. Support for ClearCase, Darcs, Monotone, Perforce and StarTeam is in progress and partly available. WWW: http://rubyforge.org/projects/rscm
