+This directory contains local additions to/overrides for the Quagga
+autoconf build system.
+
+At this time additions are:
+
+- m4 files taken from libtool CVS circa august 2004. These have been
+imported into Quagga as they are more robust with respect to configuring
+libtool support for languages which Quagga does not use. As and when libtool
+releases become commonly available with that capability, these can be
+removed. The files are:
+
+	argz.m4
+	libtool.m4
+	ltdl.m4
+	ltoptions.m4
+	ltsugar.m4
+	ltversion.m4
