 WHAT IS THIS?
 
-As a programming exercise for learning Python, I wrote a simple rwhois
-server (described in RFC 2167).  It uses in-memory data structures,
-and it intuits the schema based on the data it sees.  The server takes
-as input a schema file, which for now just describes which attributes
-should be indexed (and how), and data files which look much like the C
-rwhoisd's data files.

 This version supports a sort of extended query syntax: IP or CIDR
 queries ending in "**" will result in a "subnet" search, where all of
 the found subnets at or below the specified network will be returned.
 Ending a IP or CIDR query with a single "*" will result in a
-"supernet" search.
+"supernet" search, returning all the networks enclosing the queried
+network.  (A plain network query will return the closest enclosing
+network, including matching networks).
+
+It supports (as of v0.4) IPv6 CIDR networks and network blocks, and
+supports indexing network-block type values.  That is, you can index
+values like "10.131.10.0 - 10.131.11.255" and "3ffe:4:5::0 -
+3ffe:4:6::ffff".
