{Note: Libgpm is *the* interface for Linux text-mode programs.
Unfortunately it isn't suitable for anything else besides a blocky
cursor on a text mode interface. The GPM protocol suffers from serious
defficiencies and ideally, gpm is abolished as quickly as possible.
With lack of a good alternative, GPM deserves good support. But
please keep this in mind while coding.}
