Help("""Arguments may be a mixture of switches and targets in any order.
Switches apply to the entire build regardless of where they are in the order.
Important switches include:

    prefix=/usr     probably what you want for production tools
    build=base      build directly in the distribution root;
                    you'll need this if you're trying to use Emacs compile mode.
    build=release   build the release build variant with appropriate flags
                        in build/release and copy resulting binaries
                        into distribution/working copy root.
    build=debug     same for debug build variant, binaries will be copied with -debug suffix

With no arguments, the recipe builds wesnoth and wesnothd.  Available
build targets include the individual binaries:

    wesnoth wesnothd campaignd exploder cutter test

You can make the following special build targets:

    all = wesnoth exploder cutter wesnothd campaignd (*).
    TAGS = build tags for Emacs (*).
    wesnoth-deps.png = project dependency graph
    install = install all executables that currently exist, and any data needed
    install-wesnothd = install the Wesnoth multiplayer server.
    install-campaignd = install the Wesnoth campaign server.
    install-cutter = install the castle cutter
    install-exploder = install the castle exploder
    install-pytools = install all Python tools and modules
    uninstall = uninstall all executables, tools, modules, and servers.
    pot-update = generate gettext message catalog templates and merge them with localized message catalogs
    update-po = merge message catalog templates with localized message catalogs for particular lingua
    update-po4a = update translations of manual and manpages
    af bg ca ... = linguas for update-po
    dist = make distribution tarball as wesnoth.tar.bz2 (*).
    data-dist = make data tarball as wesnoth-data.tar.bz2 (*).
    binary-dist = make data tarball as wesnoth-binaries.tar.bz2 (*).
    wesnoth-bundle = make Mac OS application bundle from game (*)
    sanity-check = run a pre-release sanity check on the distribution.
    manual = regenerate English-language manual and, possibly, localized manuals if appropriate xmls exist.

Files made by targets marked with '(*)' are cleaned by 'scons -c all'

Options are cached in a file named .scons-option-cache and persist to later
invocations.  The file is editable.  Delete it to start fresh. You can also use a different file by
specifying --option-cache=FILE command line argument. Current option values can be listed with 'scons -h'.

If you set CXXFLAGS and/or LDFLAGS in the environment, the values will
be appended to the appropriate variables within scons.
