--* version 0.7 *--
Output files are now named according to David Madore's sceme,
involving the md5-sum of the data.

--* version 0.6 *--
Now works on FreeBSD (tested on 4.0-STABLE); other systems
should also work now. Code cleanups and documentation
improvements.

--* version 0.5 *--
Pad now uses OpenSSL as a source for random bytes. This should
increase security, especially on operating systems that use a
linear-type alorithm to implement /dev/urandom.

--* version 0.4 *--
No longer forces output to be written to a file. It can write
to stdout, which is useful when being called from a shell
script or other program. Code cleanups.

--* version 0.3 *--
Code cleanups and minor bugfixes.
