Re: Keyword substitution ($Id$)

Keyword substitution, in CVS and elsewhere, is an entirely client-side
issue. The reason you get merge conflicts is that merges are also
entirely client side (commit comes after the working-copy merge). You
can avoid keyword conflicts by specifying no keyword expansion in the
working copy.
