	DOC_CONTENTS="${DOC_CONTENTS}
You have to put /${mylibdir}/libmediaclient.so into /etc/ld.so.preload
or to export LD_PRELOAD=\"/${mylibdir}/libmediaclient.so\"
before you start a multimedia applications like mplayer or mpv which should
be able to access the sundtek device.

This happens with USE=ld-preload-file or with ld-preload-env (in the global
environment), respectively.

However, such a global setting in some cases this gives warnings when
32-bit applications are used.

Thus, it might be a good idea to do it only locally by writing
corresponding wrapper scripts for those multimedia applications you
want to use with sundtek-tv.
