     Re: Reporting and Graphing in nocol

One feature that I was hoping would be nice (it wasn't around in
previous versions, I don't believe it is in 4.2), is the ability to type 
'nocol -s' or some other flag that will print out the current nocol
screen (perhaps another flag for long format), that I can pipe into a
script, and manipulate for other purposes (e.g. finger info, or to hook
it up with a multipart/mixed html script for realtime updates), etc.
