I'll admit I wasn't entirely clear on the licensing.  The C source file says:

 * By: David J. Schwartz
 * <davids at webmaster.com>
 * Version 1.03
 *
 * Put into the public domain. Please keep the acknowledgement above
 * intact. Portions taken from the NTP source (the time_shm structure
 * and attach_shm code) are covered by the NTP copyright/license

Does including a structure and one function mean the whole thing falls under
the NTP license (I looked at the NTP source and that file is MIT licensed)?  I
wasn't sure; that's why I left it as claimed above (but I'm not a lawyer and I
suspect the above author is not either).

I'll get the other things cleaned up pending a licensing review.  How does this
look for a description:

===
Shared memory (SHM) driver to allow high-resolution pulse-per-second
(PPS) time sources to be used with a Network Time Protocol (NTP) server
without a PPS-enabled kernel.  The PPS pin of the time source must be 
connected to the declared signal pin on a serial or parallel port.

See /etc/sysconfig/shmpps for configuration.
===

And yes, I need to get more involved in the reviews (haven't done one yet).
