Easystroke is a gesture-recognition application for X11.  Gestures or strokes 
are movements that you make with you mouse (or your pen, finger etc.) while 
holding down a specific mouse button.  Easystroke will execute certain actions 
if it recognizes the stroke; currently easystroke can emulate key presses, 
execute shell commands, hold down modifiers and emulate a scroll wheel. 

The program was designed with Tablet PCs in mind and can be used effectively 
even without access to a keyboard. Easystroke tries to provide an intuitive 
and efficient user interface while at the same time being highly configurable
and offering many advanced features.

Easystroke requires gtkmm.

If you'd also like the manpage installed, then help2man needs to be installed 
and then pass COMPILE_MAN=yes to the slackbuild.
