# This is subject to the GPL (as stated above in german) and does the
# substitutions done by configure (actually, recent autoconf versions do not
# replace everything until build time;  the built script does build time
# replacement.  DO NOT reorder the SUBSTNAMES unless you know what you are
# doing!
#
# Tries to extract some configure substitutions from $CONFIGURE_AC and
# is not very intelligent about its syntax.  Maybe better use autoconf -t ..
