GPM-1.20.7
Introduction to GPM
The GPM (General Purpose Mouse
daemon) package contains a mouse server for the console and
xterm. It not only
provides cut and paste support generally, but its library component
is used by various software such as Links to provide mouse support to the
application. It is useful on desktops, especially if following
(Beyond) Linux From Scratch instructions; it's often much easier
(and less error prone) to cut and paste between two console windows
than to type everything by hand!
This package is known to build and work properly using an LFS-11.2
platform.
