i always do a useability test.  this is one of those cases where ok() does
not do the trick.

from Test::More man page:
     You usually want to test if the module you're testing loads ok, rather
than just vomiting if its load fails.
     For such purposes we have "use_ok" and "require_ok".

Note the modeline for emacs and vim.  test files normally end with .t, and
neither vim nor emacs automatically detect them as perl.

modelines can usually go in the first 5 or last 5 lines.

# -*- mode: perl -*-
# vim: set expandtab autoindent nows sts=2 sw=2:

use Test::More tests => 2;

## this tests the useability of the package


my $version = $Compress::Bzip2::VERSION;
ok( $version, "Compress::Bzip2 version is $version" );
