NAME
    Module::Build::Pluggable::Fortran - Plugin for Module::Build to compile
    Fortran ".f" files

VERSION
    version 0.27

SYNOPSIS
        # Build.PL
        use strict;
        use warnings;
        use Module::Build::Pluggable ('Fortran');

        my $builder = Module::Build::Pluggable->new(
            dist_name  => 'PDL::My::Module',
            license    => 'perl',
            f_source   => [ 'src' ],
            requires   => { },
            configure_requires => {
                'Module::Build'                      => '0.4004',
                'Module::Build::Pluggable'           => '0',
                'Module::Build::Pluggable::Fortran'  => '0.20',
            },

        );
        $builder->create_build_script();

DESCRIPTION
    This is a plugin for Module::Build (using Module::Build::Pluggable) that
    will assist in building distributions that require Fortran ".f" files to
    be compiled. Please see the Module::Build::Authoring documentation if
    you are not familiar with it.

    Add Prerequisites
            build_requires => {
                'ExtUtils::F77'      => '0',
                'ExtUtils::CBuilder' => '0.23',
            },

        You can, or course, require your own versions of these modules by
        adding them to "requires =" {}> as usual.

    Compile ".f" files
        The directories specified by the f_source array within your
        distribution will be searched for ".f" files which are, immediately
        prior to the build phase, compiled into ".o" files. This is
        accomplished (effectively) by running:

            my $mycompiler = ExtUtils::F77->compiler();
            my $mycflags   = ExtUtils::F77->cflags();
            system( "$mycompiler -c -o $file.o $mycflags -O3 -fPIC $file.f" );

    Add Extra Linker Flags
            extra_linker_flags =>  $PDL::Config{MALLOCDBG}->{libs}
              if $PDL::Config{MALLOCDBG}->{libs};
            extra_linker_flags => ExtUtils::F77->runtime, <your fortran object files>

        Adds the linker flags from "ExtUtils::F77" and all the ".o" object
        files created from the ".f" Fortran files.
