      You can always inline image using uuencoded or similar ascii friendly encoding.

      cat /usr/share/doc/perl-IO-stringy-2.108/icons/itembullet.gif | perl -0777 -e
      'print pack("u", <>)' | perl -0777 -e 'print unpack "u", <>' > out.gif

      so you convert the binary image into a uuencoded string:

      $ cat foo.gif | perl -0777 -e 'print pack("u", <>)'

      (-0777 is the same as 'local $/' to slurp the whole thing in)

      Now you inline this uuencoded string into a variable in your test and convert
      it to the binary format at run time:

      $uuencoded = <<EOUU;
      $binary = unpack("u", $uuencoded);

      then you can send this image as if it was a file on the disk.

      perl -V is not enough, I ask people to follow the guidelines for a reason :)

      also the next version of mp2 will sport mp2bug script (it's in cvs already).

      Dunno if I get to build it. May be tomorrow. Meanwhile a self-containing test
      would be cool.

      Is it hard to write a short test? I haven't used Filter::CBC yet. So I won't
      have to mess with the magic install.

      probably complaining about:

      our $VERSION = 0.1;

      does it help to use "0.1"?
