+    * There are three levels of tradeoff of speed vs memory
+    * Because java has no preprocessor), they are written as three separate classes from which to choose
+    *
+    * The fastest uses 8Kbytes of static tables to precompute round calculations), 4 256 word tables for encryption
+    * and 4 for decryption.
+    *
+    * The middle performance version uses only one 256 word table for each), for a total of 2Kbytes),
+    * adding 12 rotate operations per round to compute the values contained in the other tables from
+    * the contents of the first
+    *
+    * The slowest version uses no static tables at all and computes the values in each round

+# Structure of a match: [Match] Followed by the match and action
+# The match can be a simple match or an advanced regular expression
+# You can use $u for username of the player triggering the match
+# You can define an action if the match was in a private message
+# You can define an action if the match was not sent by a player
+# Regex matches are also supported eg $1, $2, $3.. in actions
+
+# Simple example: Respond to a message containing a keyword
+
+[Match]
+match=hi
+action=send hi, $u!
+actionprivate=send /tell $u Hello!
+actionother=log detected "hi" message
+
+# You do not need to specify all the "action" fields
+# Only one of them is required for each match
+
+# Advanced example: Use a regular expression
+# Here a "regex" field is used instead of "match" field
+# Do not use both "regex" and "match" fields...
+
+[Match]
+regex=^.*hello ([a-zA-Z0-9_]+).*$
