Multi-player classic air combat simulator

A multi-player aerial combat simulation. Players engage in air to air combat against one another using heat seeking missiles and cannons.

Main features include:

 * Simulation with 6 degrees of freedom.
 * Tricycle and bicycle landing gear simulation.
 * Structural limit to the vertical positive/negative load.
 * Standard atmosphere.
 * Weather: daylight/night, fog, wind.
 * Classic instruments, including magnetic compass, turn and slip
   indicator, airspeed indicator, attitude and bank indicator,
   altitude indicator, vertical speed indicator.
 * Navigation: HSI with RNAV calculator, ADF.
 * Head-up display (HUD) and inertial reference system.
 * Auto-pilots: hold altitude, hold climb rate, hold speed, follow VOR
   radial, follow ILS glide path, rudder/ailerons coordination.
 * Several aircraft models implemented, both civil and military.
 * Two sceneries provided: Dallas area (Texas) and Italy area with
   hundreds of runways and radio stations.

acm runs under the X window system. This version of acm is implemented as a distributed simulation. It communicates information via the IEEE Distributed Interactive Simulation protocol.

The original version of acm was written by Riley Rainey. This is Umberto Salsi's updated version.
