#	$NetBSD: configure.ac,v 1.82.2.1 2015/04/22 07:18:58 snj Exp $
#
# Autoconf definition file for libnbcompat.
#
# When you edit configure.ac:
# 0. Create the tools versions of autoconf and autoheader:
#        cd ${SRCDIR} && build.sh -V MKMAINTAINERTOOLS=yes tools
#    (This might not work if you try it after editing configure.ac.)
# 1. edit configure.ac
# 2. Regenerate "configure" and "nbtool_config.h.in" from "configure.ac":
#        cd ${SRCDIR}/tools/compat && ${TOOLDIR}/bin/nbmake-${MACHINE} regen
#    (Please don't use a non-tools version of autoconf or autoheader.)
# 3. Test that the tools still build:
#        mv ${TOOLDIR} ${TOOLDIR}.bak
#        cd ${SRCDIR} && build.sh -V MKMAINTAINERTOOLS=yes tools
# 4. cvs commit files that you edited.
# 5. Regen again, to pick up changed RCS IDs from the above commit:
#        cd ${SRCDIR}/tools/compat && ${TOOLDIR}/bin/nbmake-${MACHINE} regen
# 6. cvs commit files that were generated.
