+# The nicks that match will be turned into notices, useful for marking
+# bots as such. Note that if the nicks start with ~ the rest is taken
+# to be a regex. Due to limitations of our dummy parser you can't use
+# {x,y} character classes or other regex constructs that require a
+# comma, but usually that's something you can work around.
