$0 -- Test packages in crosstool-NG

Verifies that the release tarballs can be downloaded for the packages
available in crosstoo-NG and check that the patches apply cleanly.
Requires crosstool-NG to be configured and built prior to running.

Options:
    --help, -?
        Display this help message.

    --download, -d
        Download all packages to the default directory (\$HOME/src).

    --digest, -D
        Create digests (MD5/SHA-1/...) for all package archives.

    --apply-patches, -a
        Implies -d. Unpack and apply the bundled patches.

    --update-patches, -P
        Implies -d. Renumber the patches and update the offsets
        in them. Requires quilt to be installed.

    --verify-urls, -u
        Check *all* the download URLs for accessibility, without
        actually downloading anything.

    --select MASK, -s MASK
        Specify the package to operate upon. MASK can be either package
        name ("-s foo"), or package name + version ("-s foo-1.1").

    --signature, -S
        When downloading archives (because of any of -D/-d/-u options),
        also download/verify signatures.
