Splitting Apache log files

[Bradley Miller]

I've run into a situation, I've got all my log files in one "BIG" 
logfile.  I want to run Webalizer and get stats info for clients, I managed 
to get stats to run for one client today (yea), but they had a separate log 
file.  I know the Apache Split-Logfile script is there, but how does one go 
about using it?   It theoretically should make all my little log files by 
domain so I can give my hosting customers stats . . .

Also, I just want to note that I kept everything in one big log file 
because of conflicting information here and there.  Some say you'll run out 
of file handles (with 2.2 kernel ? ? ) and some say you are ok with newer 
kernels.  Nobody ever says "here's how you do it and why" . . . it's all 
sorta wishy washy and never a definitive source of info.   That's one minor 
frustration with Linux in general.   At least Microsoft has one central 
"this is why our software is crap" page that is the gospel.
