#########################################################################
#
# CONFIGURATION
#
# There are three forms of configuration:
#
#       1) edit the viewvc.conf created by the viewvc-install(er)
#       2) as (1), but delete all unchanged entries from viewvc.conf
#       3) do not use viewvc.conf and just edit the defaults in this file
#
# Most users will want to use (1), but there are slight speed advantages
# to the other two options. Note that viewvc.conf values are a bit easier
# to work with since it is raw text, rather than python literal values.
