This signature file may be used to cryptographically verify file integrity,
like this::

    $ gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xA16EB94D
    $ gpg --list-keys 0xA16EB94D
      pub   2048R/A16EB94D 2008-08-15 [expires: 2023-08-12]
      uid   Turnkey Linux Release Key <release@turnkeylinux.com>

    $ gpg --verify turnkey-bambooinvoice-12.1-squeeze-amd64-xen.tar.bz2.sig

For your convenience we also include file checksums:

    * sha1sum  b54dbb06437c908485539c8b2cd9dbf3792cbf88
    * md5sum   b6d3280f0fcf5e975379390c3356f0f6

You can calculate these on your end and compare to check for errors, but
cryptographic verification is recommended for security reasons.
