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