# This is a replacement for the old svnlastchange script, with a bit
# more of functionality.
#
# The old one was:
# svn log -r COMMITTED "$*"
# svn diff -r PREV:COMMITTED "$*" || \
# echo >&2 "Error retrieving diff: the file was probably added in the last revision"
#
# =====================================================================
# Turn on warnings the best way depending on the Perl version.
