+.TH tuxfootball 6 "November 2012" "Tux Football" "Tux Football(6) manpage"
+.SH NAME
+tuxfootball \- great 2D soccer (sometimes called football) game 
+.SH SYNOPSIS
+.B tuxfootball
+[\fIOPTION...\fR]
+.SH DESCRIPTION
+.PP
+\fBTux Football\fP brings old style gameplay from DOS times back to the desktop
+with up to date graphics! Its gameplay is similar to old classics such as
+Amco's Kick Off and Sensible Software's Sensible Soccer. 
+
+The gameplay is designed to be quick, responsive and fun. You are always in
+control of the player closest to the ball. The ball is controlled via two
+different kick buttons - one for pass, and one for shoot.  Aftertouch can be
+applied to shots by quickly pressing and holding the direction you want the
+ball to bend towards. Pushing in the opposite direction to what you kicked the
+ball makes it raise into the air, pushing in the same direction as the ball
+makes it dip towards the ground.
