I think the problem is that programmers are too close to the software. The focus is put more on the "why" than the "how." Ultimately (in extreme cases), programmers don't even know how to _use_ the software, just why someone would need to execute this method, or call that function, etc.this is very true... i've been a coder for many years... close to 30 if i really count... i've also done technical
writting insofar as writting some user structural manuals but that was many years ago, too... your thoughts on the
coders being too close to the code is accurate, too... i do recognize that what is obvious to a coder may not be obvious
to a user...
as an example, i remember way back when the tandy 1000 first hit the streets... there were many many folk who diligently
followed the instructions in the manual and wiped out the only boot floppy that came with the machine... this happened
because the manual never explicitly stated to remove the boot floppy and insert a blank one... the "funniest" thing
about this situation was that it was the section starting off about making backup copies of the boot floppy in case
something happened to it and the original was unusable! ;) ;) of course, that was only funny to those like myself that
saw the problem and couldn't believe that that one single step being left out could really cause such a situation...
anyway, my main goal in answering that post was to give that person at least one answer because i figured that not many
others would answer him... this group is pretty low traffic, ya know... i also figured that that person would reply with
a few more questions asking for further clarification... i'll also note that no one else has written an answer in the
group to that person's original question ;)

Okay, let's see, allow me to make a small answer for
The actual webalizer reports are generated in the
files "output.c" and "output.h".
The logfiles that are feeded to webalizer are parsed
in "parser.h" and "parser.c".
The nice graphs are generated in "graphs.h" and
"graphs.c". Pretty obvious until here. (From now on
I'll use something.h/c instead something.h,
Webalizer uses internally both lists and hashtables,
those are defined in "hastab.h/c" and "linklist.h/c".
"dns_resolv./hc" make the DNS resolution, to translate
IPs to hostnames.
"preserve.h/c" I believe it is for managing the
incremental mode, the histoy file, and such.
Webalizer parses the logfiles with parser.h/c, saving
the parsed information in structures which are defined
in hastab.h/c and linklist.h/c. If dns resolving is
on, it will use the functions defined in dns_resolv to
resolve the IPs. Then it uses preserve.h/c to decide
what output it should generate, and finally executes
the functions in output.h/c to generate the actual
HTML pages where you can the stats of your web server.
Basically, "parser" will fill up the hashtables and
linked lists, and "output" will simply go over them in
an ordered manner and output them in a human-readable
manner,and make some convinient calculations like
"daily average of visits" by counting all visits and
dividing by the number of days.
The rest of things are just filler designed to add
