I felt there was a hole that needed to be filled as far as searching rfc's
from a console. We have whois and nslookup right at our finger tips, why
not all the rfc's? 
the util will let you search the rfc-index for a string and return all the
related rfc's. You can then throw in a -l switch to view it, or -d to
dump it to file for offline viewing.
it's made my life easier, so i thought i'd pass it on to the public. if
you have problem with a slow web server us the -w and -u options to change
and update the servers respectively.
I've tested it on all the BSD's w/o a problem but i don't use my sunbox
much at all so it has no perl, but i have received mail from some sun
users saying it works w/o a problem. One user mentioned that he had to
change the calls to egrep to use 'gegrep'. Next release won't use grep's
at all so it will be completley portable.
any feedback/suggestions are sincerely appreciated. i feel if you're on
this list, then you should have this util.
