This is a fast-paced action strategy game for Linux implemented using 
ncurses user interface. Unlike most RTS, you are not controlling units, 
but focus on high-level strategic planning: Building infrastructure,
securing resources, and moving your armies.
The core game mechanics turns out to be quite close to WWI-WWII type of 
warfare, however, there is no explicit reference to any historical period.
