NAME
    Alien::FLTK - Build and use the stable 1.3.x branch of the Fast Light
    Toolkit

Description
    This distribution builds and installs libraries for the (stable) "1.3.x"
    branch of the FLTK GUI toolkit.

Synopsis
        use Alien::FLTK;
        use ExtUtils::CBuilder;
        my $AF  = Alien::FLTK->new();
        my $CC  = ExtUtils::CBuilder->new();
        my $SRC = 'hello_world.cxx';
        open(my $FH, '>', $SRC) || die '...';
        syswrite($FH, <<'') || die '...'; close $FH;
          #include <FL/Fl.H>
          #include <FL/Fl_Window.H>
          #include <FL/Fl_Box.H>
          int main(int argc, char **argv) {
            Fl_Window *window = new Fl_Window(300,180);
            Fl_Box *box = new Fl_Box(FL_UP_BOX, 20, 40, 260, 100, "Hello, World!");
            box->labelfont(FL_BOLD + FL_ITALIC);
            box->labelsize(36);
            box->labeltype(FL_SHADOW_LABEL);
            window->end();
            window->show(argc, argv);
            return Fl::run();
        }

        my $OBJ = $CC->compile('C++'                => 1,
                               source               => $SRC,
                               include_dirs         => [$AF->include_dirs()],
                               extra_compiler_flags => $AF->cxxflags()
        );
        my $EXE =
            $CC->link_executable(
             objects            => $OBJ,
             extra_linker_flags => '-L' . $AF->library_path . ' ' . $AF->ldflags()
            );
        print system('./' . $EXE) ? 'Aww...' : 'Yay!';
        END { unlink grep defined, $SRC, $OBJ, $EXE; }

Constructor
    There are no per-object configuration options as of this version, but
    there may be in the future, so any new code using Alien::FLTK should
    create objects with the "new" constructor.

        my $AF = Alien::FLTK->new( );

Methods
    After creating a new Alien::FLTK object, use the following methods to
    gather information:

  "include_dirs"
        my @include_dirs = $AF->include_dirs( );

    Returns a list of the locations of the headers installed during the
    build process and those required for compilation.

  "library_path"
        my $lib_path = $AF->library_path( );

    Returns the location of the private libraries we made and installed
    during the build process.

  "cflags"
        my $cflags = $AF->cflags( );

    Returns additional C compiler flags to be used.

  "cxxflags"
        my $cxxflags = $AF->cxxflags( );

    Returns additional flags to be used to when compiling C++ using FLTK.

  "ldflags"
        my $ldflags = $AF->ldflags( qw[gl images] );

    Returns additional linker flags to be used. This method can
    automatically add appropriate flags based on how you plan on linking to
    fltk. Acceptable arguments are:

    "gl"
        Include flags to use GL.

        *This is an experimental option. Depending on your system, this may
        also include OpenGL or MesaGL.*

    "images"
        Include flags to use extra image formats (PNG, JPEG).

  "branch"
        my $revision = $AF->branch( );

    Returns the SVN branch of the source Alien::FLTK was built with. This
    will always be "1.3.x".

  "revision"
        my $revision = $AF->revision( );

    Returns the SVN revision number of the source Alien::FLTK was built
    with.

Notes
  Requirements
    Prerequisites differ by system...

    Win32
        The fltk libs and Alien::FLTK both build right out of the box with
        MinGW. Further testing is needed for other setups.

    X11/*nix
        X11-based systems require several development packages. On Debian,
        these may be installed with:

            > sudo apt-get install libx11-dev
            > sudo apt-get install libxi-dev

        Additionally, the optional XCurser lib may be installed with:

            > sudo apt-get install libxcursor-dev

    Darwin/OSX
        Uh, yeah, I have no idea.

  Installation
    The distribution is based on Module::Build, so use the following
    procedure:

      > perl Build.PL
      > ./Build
      > ./Build test
      > ./Build install
