# $FreeBSD$
#
# Bring libtool scripts up to date.
#
# Feature:	libtool
# Usage:	USES=libtool or USES=libtool:args
# Valid args:	keepla	Don't remove libtool libraries (*.la) from the stage
#			directory.  Some ports need them at runtime (e.g. ports
#			that call lt_dlopen from libltdl).
#		build	Add a build dependency on devel/libtool.  This can
#			be used when a port does not generate its own libtool
#			script and relies on the system to provide one.
