+"""X-Chat 2.0 plugin to hide what ignored people say on channel.
+
+Messages from people (nicknames) that are ignored (using /ignore) are
+printed with the same foreground and background color. This is better
+than normal /ignore, since it reduces your confusion by making it clear
+that the ignored people are talking. Also, you can select the text with
+a mouse and see what they're saying, in case it is something important.
+(If you do that a lot, there's no point in using /ignore, though.)
+
+Place in your .xchat2 directory and either reload X-Chat or
+/PY LOAD whiteout.py

+0.2     15 Aug 2005     Remove ":+" and ":-" prefixes from the message of
+                        a user. I should read about the IRC protocol.
+0.1     10 Aug 2005     Initial version, based on Scott James Remnant's
+                        topicdiff.py.
