##  libperl.module -- mod_perl Apache source tree stub
##  Written by Ralf S. Engelschall <rse@apache.org>
##
##  This script is _sourced_ by Apache's src/Configure script
##  while configuring the module subdirectories. We can use
##  two variables here to find ourself: $modfile, $modbase.
##  Additionally because we run inside src/Configure's namespace
##  we can directly adjust CFLAGS, LIBS, etc.
