#
# SYNOPSIS
#
# AX_F90_MODULE(MODULE, MODULE-REGEXP, FUNCTION-BODY [, SEARCH-PATH [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])
#
# DESCRIPTION
#
# Set up the compiler flags to use a given fortran 90 module MODULE is the
# name of the module. MODULE-REGEXP is a regular expression (used by find)
# matched by the filename of the module. FUNCTION-BODY is the body of a
# function (including the 'use' statement and the call to a function
# defined by the module) SEARCH-PATH is a colon-separated list of
# directories that will be recursively searched for modules files. If
# empty, the search path will be composed of $prefix, $ac_default_prefix,
# and all directories exactly one level *above* the directories in
# $LD_LIBRARY_PATH (the rationale is that when libraries are put in
# /some/path/lib, the modules are often put in a directory like
# /some/path/include or /some/path/mod or something similar). An output
# variable named F90_MODULE_xxx will be set up with the proper flag for
# substitution in Makefiles (xxx is built from the first argument, with
# autoconf traditional escapes).
