# SYNOPSIS
#
#   AX_F90_LIBRARY_SETUP(LIBRARY, HEADER-REGEXP, MODULE-REGEXP, LIB-REGEXP, FUNCTION-BODY)
#
# DESCRIPTION
#
#   Convenience macro to set up a fortran 90 library in a simplified way.
#   LIBRARY is the name of the library. HEADER-REGEXP is a regular
#   expression (used by find) matched by the header file to look for (may be
#   empty). MODULE-REGEXP is a regular expression (used by find) matched by
#   the filename of the module (may be empty). LIB-REGEXP is a regular
#   expression (used by find) matched by the filename of the library, this
#   is useful either if the library filename does not follow the traditional
#   libxxx.a or libxxx.so pattern, or if some specific information is
#   embedded into the name, like compiler used, debugging status ...).
#   FUNCTION-BODY is the body of a function (including the 'use' statements
#   and the call to a function defined by the library).
#
#   This macro is a simple wrapper around AX_F90_MODULE and AX_F90_LIBRARY
#   that uses the parameters provided by the end user through a --with-xxx
#   option to set up the search path. Both a module and a library will be
#   tested, the same path will be used for both tests, so the path must be
#   set up with a common parent directory of both the library file and the
#   module file. The macro also automatically updates the FCFLAGS, LDFLAGS
#   and LIBS variables in addition to providing the F90_HEADER_xxx,
#   F90_MODULE_xxx, F90_LDFLAGS_xxx and F90_LIBS_xxx output variables.
#
#   Example: suppose you have /home/nostradamus/esoteric/lib/libalchemy.a
#   and /home/nostradamus/esoteric/mod/alchemy.mod which provides a function
#   transmute_into_gold, you can use the following in you configure.ac:
#
#     AX_F90_MODULE_EXTENSION
#     if test x$ax_cv_f90_modext = xunknown ; then
#       AC_MSG_ERROR([unable to find f90 modules extension])
#     fi
#     AX_F90_LIBRARY_SETUP(alchemy,[],alchemy.$ax_cv_f90_modext,libalchemy*,[
#        use alchemy
#        call transmute_into_gold('lead')
#       ])
#
#   and the user could configure your package using a command like this:
#
#     ./configure --with-alchemy=$HOME/esoteric
