-        Vanitygen can search for exact prefixes or regular expression
-        matches, so you can generate Bitcoin addresses that starts
-        with the needed mnemonic.
-
-        Vanitygen can generate regular bitcoin addresses, namecoin
-        addresses, and testnet addresses.
-
-        When searching for exact prefixes, vanitygen will ensure that
-        the prefix is possible, will provide a difficulty estimate,
-        and will run about 30% faster.
