 To dump all wall messages to stdout use:
 
-    ./wall-notify cat
+    ./src/wall-notify cat
 
 All arguments passed to `wall-notify` are used when execing the process, e.g.
 to replace all spaces with underlines use:
 
-    ./wall-notify sed 's/ /_/g'
+    ./src/wall-notify sed 's/ /_/g'
 
 To display the messages with `xmessage` use:
 
-    ./wall-notfiy xmessage -file -
+    ./src/wall-notify xmessage -file -
+
+However this will display '^M' (carriage-return) and other control characters
+in the message. For a simple wrapper script which removes those, see
+`contrib/message-helper`:
+
+    ./src/wall-notify contrib/message.sh xmessage -file -
