conky - A light-weight system monitor for X
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.
For lua scripting engine support the required dependencies are:
lua, imlib2 and tolua++
All of the above requirements are available from slackbuilds.org
To disable lua support run the build with
LUA=NO ./conky.SlackBuild
