Explode comes with some useful example code (useful in that ksb's tools need these to compile). As examples go they are pretty mundane.

Here is a list of them for you to poke through:

Adelson-Velskii Landis Height-Balanced Trees
Impress your friends with a cool sounding data structure! These RAM-based trees provide a quick average time insert, delete, find scheme and are very low overhead.

Password checking code
After a Customer gives you a password (UNIX style) how do you make sure it is the correct one? This case can tell you.

Identd C interface (TAP)
You call getpeername(2) to find the host and port, but this might tell you the login name (or hash name) of the connected user! Use only as directed.

BSD Implementation of scandir for Non-BSD systems
Just what it says. Compiles on Solaris for example.

Sorted, unique C strings
These are really cheap, I mean really cheap. Just a way to keep track of a list of unique strings so we don't repeat ourself.

Others will be added in new releases.
