#"zapmost" is used to remove an entire directory tree, *except* for certain
#specified files. Arg 1 is the tree, args 2+ are the items to keep, which can
#be files or directories at the root or deeper levels.

#example calls:
#zapmost /usr/share/locales en_us
#zapmost /usr/share/terminfo l/linux
zapmost()
{
	local rootdir
	rootdir="${1}/"
	[ ! -e  "$rootdir" ] && echo "zapmost: $rootdir not found; skipping..." && return 1
	install -d ${BUILDDIR}/zap
	local dirs
	shift
	local x
	for x in ${*}
	do
		if [ "${x##*/}" = "${x}" ]
		then
			#one deep
			mv ${rootdir}${x} ${BUILDDIR}/zap
		else
			#more than one deep; create intermediate directories
			dirs=${x%/*}
			install -d ${BUILDDIR}/zap/${dirs}
			mv ${rootdir}${x} ${BUILDDIR}/zap/${dirs}
		fi
	done
	rm -rf ${rootdir}*
	mv ${BUILDDIR}/zap/* ${rootdir}
