@majorheading 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).
