Re: time to be serious about dropping CVS
As one of the original designers of SVN, I really recommend switching
to either git or Mercurial. It takes some getting used to, but any GDB
hacker can handle that challenge. Once you switch, you will love the
speed so much you'll cry when you have to use CVS (or SVN).
Perhaps it would help to declare git usage questions from contributors
"on topic" for the GDB lists, at least for a few months, so the
developers familiar with the tools can help out the others.
