TelemetryBox/Gentoo 1.3b Help
-----------------------------

Right now you are in the TelemetryBox Console. The console allows you to
administer the box on an operating system level if physical access is
possible and also allows an easy set up of the network configuration which
might be important if something goes wrong.

The TelemetryBox has the ability to bring up an X windows Graphical
Environment using the KDE desktop. The desktop is intended for operating the
box as a workstation. Note that the desktop requires significant computing
resources. It is advisable to only use the desktop on machines that are not
under heavy load and/or that are not mission critical.

The homepage of the TelemetryBox distributrion is http://telemetrybox.biz.
