+Description: lightweight taskbar
+ Tint is a simple panel/taskbar intentionally made for openbox3, but should
+ also work with other window managers. The taskbar includes transparency and
+ color settings for the font, icons, border, and background. It also supports
+ multihead setups, customized mouse actions, and a built-in clock. Tint was
+ originally based on ttm code. Since then, support has also been added
+ for a battery monitor and system tray.
+ .
+ The goal is to keep a clean and unintrusive look with lightweight code and
+ compliance with freedesktop specification.
