  <para>Builds a simple representation of the linked track of a vehicle
such as a tank. With no command line arguments, the track command will prompt
for all the required input. The vehicle is assumed to be axis-aligned with the front in
the +<emphasis>x</emphasis> direction. A combination name for the track is built by appending a unique
number to the string track. The information about the track may be included on the
command line, and is order-dependent. The parameters are (in order):</para>
