libxss-dev - 1:1.2.3-1 main

libXss provides an X Window System client interface to the MIT-SCREEN-SAVER
extension to the X protocol.
.
The Screen Saver extension allows clients behaving as screen savers to
register themselves with the X server, to better integrate themselves with
the running session.
.
This package contains the development headers for the library found in
libxss1. Non-developers likely have little use for this package.
