\class Ir ir.h
\brief The Ir class implements basic support for sending objects over an
infrared communication link.
Both \link doclnk.html DocLnk\endlink objects and files can be
sent to another device via the infrared link using the send()
function. When the send has completed the done() signal is
emitted.
The supported() function returns whether the device supports
infrared communication or not.
