cisnlist is a utility program for creating a text list of channel information 
for use on by CISN.  It queries a list of waveservers to make a list of available 
channels, accumulates additional information about each channel from a database 
(in this case, a flat file), and produces an alphabetically sorted tabulated 
list as a text file.  e.g.

This program was created in an attempt to more easily 
keep up-tp-date with the rapidly changing Northern California Seismic Network.
I run it once a day as a cron job and distribute its output file to the multiple 
CISN partners using sendfile.
