libdmx-dev - 1:1.1.4-1 main

libdmx is an interface to the DMX extension for X, which allows a single
server to be set up as a proxy spanning multiple servers -- not unlike
Xinerama across discrete physical machines. It can be reconfigured
on the fly to change the layout, and it is presented as a single logical
display to clients.
.
libdmx allows clients to configure the layout of DMX servers by adding
and removing screens, input devices, et al.
.
This package contains the development headers for the library found in
libdmx1. Non-developers likely have little use for this package.
