It is a replacement for the standard X console. Contool will flash its
icon and beep when messages are written to the icon, so you can keep it
closed on your desktop until a message arrives. You can modify this
beeping and flashing behavior; see the man page for more details.
You can instruct contool to filter and ignore certain common console
messages or act upon them.
