-"""md5crypt.py - Provides interoperable MD5-based crypt() function
-
-SYNOPSIS
-
-        import md5crypt.py
-
-        cryptedpassword = md5crypt.md5crypt(password, salt);
-
-DESCRIPTION
-
-unix_md5_crypt() provides a crypt()-compatible interface to the
-rather new MD5-based crypt() function found in modern operating systems.
-It's based on the implementation found on FreeBSD 2.2.[56]-RELEASE and
-contains the following license in it:

- <phk@login.dknet.dk> wrote this file.  As long as you retain this notice you
- can do whatever you want with this stuff. If we meet some day, and you think
- this stuff is worth it, you can buy me a beer in return.   Poul-Henning Kamp
