Hi List!
I've redesigned the editcap manpage, so that it is more useful IMHO.
What I've done:
1.) move the input / output file formats into it's own section
2.) move the option explanations from the Description into the Option 
section
3.) rephrased a lot of sentences to shorten/clarify them
4.) add option parameter names to the Options section "packets per file" 
which makes it far better readable
5.) renamed frame -> packet and record -> packet
To 1.) it might not be the most interesting thing to see the supported 
capture file formats as the first information. Someone using editcap 
might already know this and the one that don't know it might not be 
interested. Unfortunately, the list of formats doesn't seem to be 
updated when new formats are added to wiretap, so it might be a better 
idea to add a new wiretap manpage which would contain the file formats 
and detailed description of them. The editcap and all the other manpages 
could link to this wiretap manpage.
To 2.) It doesn't seem to make much sense to describe all the options in 
the description section and only put a single line in the options 
section. I've had a look at some other manpages, all of them uses the 
form I've used now.
One question remain: while the usage output of editcap prints <> for the 
options (which is correct IMHO), the manpage doesn't use <>. Example: 
[-c <packets per file>] vs. [-c packets per file]. What is correct here?
You may recompile, have a look at the file doc/editcap.html and send 
feedback.
I'm going to change the other manpages following the current scheme in 
the next days if no "vetoes" come along.
