The Mousetweaks package provides mouse accessibility enhancements for
the GNOME desktop. These enhancements are:

1. It offers a way to perform the various clicks without using any
hardware buttons.

2. It allows users to perform a right click by doing a click & hold
of the left mouse button. (For a left-handed mouse user, the terms
left and right have to be inverted.)

3. It provides an applet that the user can install on a panel. This
applet creates an area on the panel into which the pointer can
be captured until the user releases it with a predefined button
and modifier combination.

The options can be accessed through the Accessibility tab of the
Mouse Preferences of the GNOME Control Center or through the command-line.
