If you mind the traffic, or want to build an RFC collection
incrementally, you may want to use my caching version of the recently
posted program.  You have to modify the RFCDIR variable to a suitable
cache directory (should be world-writable with the sticky bit set if
your system provides this feature).

# File Name:	rfc
# Description:	retrieve RFC's automatically from uunet
# Author:	Steve Hayman (sahayman@iuvax.cs.indiana.edu)
# Date Created:	11-Apr-91

# rfc NNN
# retrieve rfc NNN from uunet, put it on stdout
# assumes rfc's are in uunet:/rfc/rfcNNNN.Z
#
# Actually the uunet people would prefer it if you ftp'd things
# from 'ftp.uu.net', so we retrieve things from that machine.
#
# uunet conveniently has files called "index" and "rfc-index"
# in the /rfc directory, so this script will also let you
# retrieve those.

# I made the following modification: The RFC is first searched in the
# ${RFCDIR} directory in either compressed or uncompressed form.  If
# it is not found there, the compressed version is first retrieved
# from ${FTPSERVER} (defaults to ftp.uu.net) and stored in the cache
# directory.  You should have write access to the cache directory.
