+# Special target to automatically make libtool using ports use the
+# libtool port.  See above for default values of LIBTOOLFILES.
+#
+# This target works by first checking the version of the installed
+# libtool shell script, which is not actually used.  Rather its path
+# is determined, and used to find the path to ltconfig and ltmain.sh
+# (which is ../share/libtool/).  Then the configure script is copied
+# and the default paths for ltconfig and ltmain.sh (normally ./) is
+# replaced.  The port's configure script therefore uses the files
+# installed by the libtool port in place of it's own.
+#
+# Also passed to ltconfig are ${LIBTOOLFLAGS}, which can be used to
+# customise the behaviour of the port.  Besides the normal flags the
+# freebsd port of libtool supports three special flags:
+#  --disable-ltlibs		Don't install the .la files. (on by default)
+#  --release-ignore		Ignore any -release flags. (off by default)
+#  --release-suffix		Add the -release to all libraries, not just
+#						the shared library. (off by default)
