# enable-all-evolved-rules - ensure that all evolved rules are active in a file
#
# usage: enable-all-evolved-rules rules/50_scores.cf > rules/51_newscores.cf
#        mv rules/51_newscores.cf rules/50_scores.cf
#
# Note: this will even enable network rules in the non-net scoresets.
# However, this should have no effect, since those check their network
# status before running anyway.  More serious is the proprietary tests;
# these will also become enabled.  Some manual fixup afterwards is
# required.
