# USAGE: autogen.sh [configure options]
#
# If environment variable DRYRUN is set, no configuring will be done -
# (e.g. in bash)  DRYRUN=1 ./autogen.sh
# will not do any configuring but will emit the programs that would be run.
#
# This script is based on similar scripts used in various tools
# commonly made available via CVS and used with GNU automake.
# Try 'locate autogen.sh' on your system and see what you get.
