#define	GLOG_VERSION "Gopher Log Analyzer 3.3"

/* Version 3.3 7/20/93 jdc@selway.umt.edu
 * fixed up main() routine so that: errors on the command line (or -h as
 * first parameter) cause glog to print the help information and abort.
 * fixed up PrintHelp() routine so help message is more understandable
 * changed FILETYPE character from ' ' to 'I' (What about Image?)
 *
 */
/* Version 3.2 
 * Fixed a small bug with search
 */
/* Version 3.1  7/11/93
 * by: Andy Wick - awick@csugrad.cs.vt.edu
 * Added supported for the "missing" gopher types, time plots, month
 * reports and several other things that I forgot :)
 * Used unprotize from gnu to unprototype the functions for external
 * distrubition.  (My version still has prototypes)
 *
 * Version 3.0 
 * by: Andy Wick - awick@csugrad.cs.vt.edu
 * This version is an almost TOTAL rewrite of glog.  It now reads all
 * the information into memory before it does ANYTHING.  It then goes
 * through the arguments one at a time.  So inorder to effect something
 * you must change it before the report.  ie.  Argument order matters now.
