What is it:
   glog will allow you to analyze your gopher log files.  Hopefully
supplying you will useful reports/plots/histograms.  It is very easy
to use, and compile.  It should compile with any standard ansi compiler,  
and now it should even work under VMS. (thanks Dennis R. Sherman)

To compile: (assuming gcc)
   gcc glog34.c -o glog

How to use:
 glog -h will display the options :).  But as a short example.  

 To create a [H]ost report, a [D]ata report with detail of [H]osts and
 width of 132, a plot of [T]ypes with basename of "test", and finally
 a histogram of t[I]mes.  The log file is called gopher.log.  Don't forget, 
 reports always go to stdout, unless the -o options is used.

 % glog -rH -w 132 -rDH -f test -pT -gI < gopher.log | more

Tested on:
 Amiga DOS, SunOS 4.1.3 (purify 2.0.3), Ultrix 4.2A
 gcc 2.3.3 and higher was used on all platforms.

Features:
 * The command line is parsed as the reports/plots/histograms are generated, 
   so that it is possible to change options for each separately.  But options
   are NOT reset for each new one.

 * Produces reports/plots/histograms on the [D]ata, [H]osts, day of the [W]eek,
   data [T]ypes, T[I]me, and [M]onth/date sorted (ie. sorted by date).

 * Produces detailed reports on any thing you can produce a normal
   report for.  Yes, you can even produce a host detail report of a 
   hosts report. (But it doesn't do you much good :)

 * Change the width of the reports.

 * You can specify the filename for plots, it defaults to gopher. (The 
   program appends a .dat, and and .run to the name)

 * You can request as many plots as you want. (But remember to change the
   filename or you will overwrite the last plot)
   
 * The program is now a lot easier to add new types of reports to, you
   only need to add 3 short routines, a variable, and edit 2 functions.
   (Well, maybe it is simple for me. :)

 * Can select starting and ending month. (Sorry no wrap around)

 * Average/Estimating can be done with the -aX option.  Possible values
   for "X" are [E]verything (default), [Y]ear, [M]onth, [W]eek, [D]ay, and [H]our

   bug fixes and enhancements: 
      Andy Wick - awick@csugrad.cs.vt.edu
      John-David Childs - jdc@selway.umt.edu
      Dennis R. Sherman - dennis_sherman@unc.edu

   * improved coding efficiency in ProcessLine()
   * fixed bug when identifying FTP type to include ftp-vms: and
        ftp-nopasv: strings used by the NOPASV patch
   * allows DEFINING whether you want to output the text users searchs for
   * works under VMS
   * added histogram support
   * added averaging/estimating support
   * added input/output files options
   * fixed up this file and comments

3.3  7/20/93
   bug fixes:  John-David Childs - jdc@selway.umt.edu

   * Fixed up main() routine so that: errors on the command line (or -h
   as the first parameter) cause glog to print the help information and
   abort.
   * Fixed PrintHelp() routine so help message is more understandable.
   * changed FILETYPE character from ' ' to 'I' (What about Image?)
   
3.2 7/19/93
   Andy Wick - awick@csugrad.cs.vt.edu
   Slight bug in ProcessLine dealing with searches fixed.

3.1 7/17/93
   Andy Wick - awick@csugrad.cs.vt.edu
   adds some features of the old glog that were removed by mistake.
   * Supports all known log entries now. (I was missing search, binary,
      and someothers)
   * Can now have a tIme report
   * The report presentation is a little better
   * Can specify a starting and ending month for the whole command
   with -s <num> and -e <num>.  These are the only options that
   are used for the WHOLE command.  The rest are from left
   to right.

TODO:
 * Fix up plots some more
 * Make some documentation
 * Improve error checking
 * Allow wrap around starting/stoping months.

If anyone has any ideas or suggestions please send them to me.
