# To do:
#  - Parse the ,v yourself instead of using rlog output, since people
#	sometimes paste rlog output into commit entries, making it impossible
#	to parse.
#  - Figure out how to do directory-wide diff's (get named tags cheaply?)
#
# Maybe:
#  - Port it to guile-scsh or scheme48-scsh
#  - compile or `undump' the perl version

# Read the configuration data.
