Maintenance and development of [Tcl]'s core is itself a substantial project, one which certainly benefits from disciplined use of [SCM] tools. As of July 2003, [SourceForge] has hosted this work (for several years?). There's sentiment to relocate Tcl's home to another technology ''and'' another site, because [[enumerate reasons]]. As [CL] understands matters, [BitKeeper] and [CVSTrac] are under consideration. [PT] - Bugzilla provides an extremely good bug tracking system that is highly configurable and significantly better than the SourceForge trackers. I don't see much need to move away from a CVS based version control system. Bitkeeper is more efficient but imposes a barier to new contributors (ie: it costs). The Tcl code base really isn't large enough to demand the increased efficiency over CVS.
