+# SYNOPSIS
+#
+#   AX_LIB_METIS([ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
+#
+# DESCRIPTION
+#
+#   This macro searches for the METIS library in the user specified
+#   location. The user may specify the location either by defining the
+#   environment variable METIS or by using the --with-metis option to
+#   configure. If the environment variable is defined it has precedent over
+#   everything else. If no location was specified then it searches in
+#   /usr/lib and /usr/local/lib for the library and in /usr/include and
+#   /usr/local/include for the header files. Upon sucessful completion the
+#   variables METIS_LIB and METIS_INCLUDE are set.
+#
+#   ACTION-IF-FOUND is a list of shell commands to run if a METIS library is
+#   found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it is
+#   not found. If ACTION-IF-FOUND is not specified, the default action will
+#   define HAVE_METIS. If ACTION-IF-NOT-FOUND is not specified then an error
+#   will be generated halting configure.
