This is a very small set of tools for finding and reading RFCs.  These tools
demonstrate why I like Unix so much:  it's easy to put together things like
this.

If you want to actually use these, you need to:
1) install them somewhere in your path
2) make sure perl is in /usr/bin
3) make sure gzip is in your path
4) put a gzipped copy of the RFC index in /usr/doc/rfc/rfc-index.txt.gz,
	or change rfc-index to point to where it really is
5) get netcat from somewhere, and install it in your path.

Example usage:
kragen@gentle:~/scripts> rfc-index URN
2169 A Trivial Convention for using HTTP in URN Resolution. R. Danie1.
     June 1997. (Format: TXT=17763 bytes)

2141 URN Syntax. R. Moats. May 1997. (Format: TXT=14077 bytes)

kragen@gentle:~/scripts> rfc 2141 > /tmp/rfc-2141.txt
kragen@gentle:~/scripts> less /tmp/rfc-2141.txt
...

Anyway, here they are.
