      3 # Autoconf definition file for make.
      4 #
      5 # When you edit configure.ac:
      6 # 0. Create the tools version of autoconf:
      7 #        cd ${SRCDIR} && build.sh -V MKMAINTAINERTOOLS=yes tools
      8 #    (This might not work if you try it after editing configure.ac.)
      9 # 1. edit configure.ac
     10 # 2. Regenerate "configure" from "configure.ac":
     11 #        cd ${SRCDIR}/tools/make && \
     12 #        ${TOOLDIR}/bin/nbmake-${MACHINE} -f Makefile.regen
     13 #    (Please don't use a non-tools version of autoconf).
     14 # 3. Test that nbmake still builds
     15 #        mv ${TOOLDIR}/nbmake ${TOOLDIR}/bin/nbmake.bak
     16 #        cd ${SRCDIR} && build.sh makewrapper
     17 # 4. cvs commit files that you edited.
     18 # 5. Regen again, to pick up changed RCS IDs from the above commit:
     19 #        cd ${SRCDIR}/tools/make && \
     20 #        ${TOOLDIR}/bin/nbmake-${MACHINE} -f Makefile.regen
     21 # 6. cvs commit files that were generated.
