Towards automake XI patch from Ralf Corsepius <corsepiu@faw.uni-ulm.de>:

    This patch is the most scary of all proposals I've been mailing to you
    this week until now.

    It consists of 3 parts:
        1. a patch
        2. a perl script (acpolish)
        3. a shell script wrapper to invoke the perl-script.

    The perl-script reads in each Makefile.in and modifies them
    ("polishes/beautifies" them :-).

    These modifications are not easy to describe:

    Basically, it hard-codes some automake Makefile-variables and rules into
    RTEMS autoconf-Makefile.ins (Note: autoconf vs. automake!!) and converts
    some settings/variables to configure scripts' requirements (Yes,
    plural).

    E.g. it adds the automake standard variables $top_builddir and $subdir,
    adds dependency rules for automatic re-generation of Makefiles from
    Makefile.in, adds support variables for relative paths to multiple
    configure scripts etc.


    The patch is a one-line patch to enable the support of the new features
    added by acpolish.

    The shell script is a wrapper which pokes around inside of the source
    tree for Makefile.ins and invokes acpolish on all autoconf-Makefile.ins.

    acpolish is designed to be able to run several times on the same
    Makefile.in and may once become a more general tool to convert RTEMS
    Makefile.in to automake. Therefore, I'd like to keep it inside of source
    tree. (e.g. as contrib/acpolish or c/update-tools/acpolish). However, it
    doesn't make sense to export it outside of RTEMS.


To apply this:

    cd <source-tree>
    patch -p1 -E < <path-to-patch>/rtems-rc-19990318-1.diff
    tar xzvf <path-to>/rtems-rc-polish.tar.gz
    ./rtems-polish.sh
    ./autogen

    Note: The path contrib/acpolish is hard-coded into rtems-polish.sh, if
    you decide to put it in an alternative place, please modify
    rtems-polish.sh to reflect this change.

    Later:
    cvs rm make/rtems.cfg (It isn't used anymore)
    cvs add contrib
    cvs add contrib/acpolish
    cvs commit

    I've tested this intensively, but naturally I can't exclude bugs.

    Ralf.

    PS.: Most probably, this is the last "Towards automake" patch. The next
    one probably will be a real automake patch.
