Conky is a system monitor for X originally based on the torsmo code.
Since it's original conception, Conky has changed a fair bit from
it's predecessor. Conky can display just about anything, either on
your root desktop or in it's own window. Conky has many built-in
objects, as well as the ability to execute programs and scripts, then
display the output from stdout.
To enable lua scripting engine support, you will need lua, imlib2, and
tolua++, and run this script like this: LUA=yes ./conky.SlackBuild
