Re: [PATCH] Change file names in text-base and prop-base

From: Kevin Pilch-Bisson <kevin_at_pilch-bisson.net>
Date: 2001-11-15 14:31:28 CET

Does anyone still have any objections to this patch? (Other than the
fact that my define was actually as ".base-svn" instead of ".svn-base"). If
I don't hear anything, I will commit this later today, update the conversion
shell script and post it again.
