What is it:
   glog will allow you to analyze your gopher log files.  Hopefully
supplying you will useful reports/plots/histograms.  It is fairly 
easy to use, with plenty of options.  It can generate almost any kind 
report that you would want.  This is probably going to be the last 
version of glog, at least by me.  There are lots of other nice utilities 
that do this very same thing.  Plus I am applying to graduate schools now.

It should compile with any standard ansi compiler, and now it should even 
work under VMS. (thanks Dennis R. Sherman)

To compile: (assuming gcc)
   1) Edit glog35.c and look at the configuration section.  There are
      four options that you can play with, but the defaults should
      be fine.
   2)
      gcc glog35.c -o glog


 glog -h will display the options :).

Examples: 

% glog35 -sn -gO < gopher.log | more
     Print out a domain graph sorted by the domain name field to stdout

% glog35 -pT < gopher.log | more
     Generate a gnuplot file with type information

% glog35 -aY -sH -rD -i gopher.log -o gopher.out
     Generate a report sorted by the reverse number of hits, 
     average the data as if there was a years worth, and save it
     to a file called gopher.out

Tested on:
 Amiga DOS, Solaris 2.3, 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, D[O]main and [M]onth/date sorted (ie. sorted by date).

 * Can sort reports by name forward/backward or by hits forward/backward

 * 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
