The RAPI library is an open source implementation that works like RAPI.DLL,
available on Microsoft operating systems. The library makes it possible to make
remote calls to a computer running device. Documentation for the RAPI calls
is available at this address:

In order to use librapi, a daemon that the device client connects to must be
running on the computer using librapi.

This requires libsynce.
