* This is really a "preview" of my forthcoming encryption library. The
* real deal will be much snazzier and cook your breakfast too. Heck, it
* might even have comments, too! For now, if you'd like to get into the
* encryption scene a bit, feel free to take this baby for a spin. The
* simple interface is documented below. Dig into the code if you want
* to try some more advanced things.
*
* Expect all of this to change significantly before the final release!
*
* Usage:
*
* This library implements the RC5 encryption algorithm, originally
* developed by RSA, Inc. It encrypts and decrypts data as text
* strings: if your data is not yet in text format, you'll have to
* provide your own method for translating it to and from text.
* In the specific case of encrypting savefiles, you'll probably
* want to look at savefile.ExportText() and savefile.ImportText().
*
* RC5 encryption uses a key, or password, to secure data against
* attack. To encrypt a plain text string p using key k and store
* it as cipher text c, simply call:
*
* c = RC5_Encrypt(p, k)
*
* Similarly, to decrypt a cipher text string c using key k into plain
* text p, call:
*
* p = RC5_Decrypt(c, k)
*
* By definition, RC5_Decrypt(RC5_Encrypt(p, k), k) == p.

* You can compile this library standalone to get a simple demo world.
* Examine the demo code, play with the verbs, have fun.
