11# The gate status display.

13# This module contains the \ref FleetGateStatus widget, which is the tab
14# displaying the status of the MAVA Fleet and the gates at LHBP. The left side
15# of the widget is the table with the list of the planes and their states. The
16# right side displays the numbers of the gates and their occupation status.
