"""
Utility to simplify finding handles in one of the pseudo-RIR databases.
Usage: python csvgrep.py datum [datum ...]
where each datum is an ASN, IP address, or IP prefix.
ASNs are recognized by being pure integers; IP addreses are recognized
by having dots (IPv4) or colons (IPv6).
After eating all of the command line arguments, we search asns.csv for
any ASNs given, and prefixes.csv for any prefixes given.
