logtool (log analyzer)

Logtool is a command line program that will parse ASCII logfiles into
a more palatable format.  It will take anything resembling a syslog 
or multilog file (this includes syslog-ng, and probably most of the 
other variants out there), and crunch it into one of the following 
formats for your viewing pleasure: 

 * ANSI (colorized for easy "at a glance" viewing) 
 * ASCII (for e-mail'ed reports, and term's that don't support color) 
 * CSV (for importing into your favorite spreadsheet/database) 
 * HTML (for generating web pages) 
 * RAW (for no good reason)
