#
# A script that symlinks source files from Mesa to modular
#
# Author: Soren Sandmann (sandmann@redhat.com) (original)
# adapted for Mesa by Adam Jackson (ajax@nwnk.net)

#
# Things we would like to do
#
#	- Check that all the relevant files exist
#		- AUTHORS, autogen.sh, configure.ac, ...
#	- Check that we have actually linked everything
#		- if a file doesn't need to be linked, then it needs
#		  to be listed as "not-linked"
#	- Compute diffs between all the files (shouldn't be necessary)
#	- possibly check that files are listet in Makefile.am's
#	- Clean target directory of irrelevant files
#

check_destinations () {
    # don't do anything - we are relying on the side
    # effect of dst_dir
    true
}

check_exist() {
    # Check whether $1 exists

    if [ ! -e $1 ] ; then
	error "$1 not found"
    fi
}

delete_existing() {
    # Delete $2

    rm -f $2
}

link_files() {
    # Link $1 to $2

    if [ ! -e $2 ] ; then
	ln -s $1 $2
    fi
}

main() {
    check_args $1 $2

    run check_destinations "Creating destination directories"
    run check_exist "Checking that the source files exist"
    run delete_existing "Deleting existing files"
