com.textflex.txtfl
Class Txtfl

java.lang.Object
  com.textflex.txtfl.Txtfl

All Implemented Interfaces:: java.lang.Runnable

public class Txtfl
extends java.lang.Object
implements java.lang.Runnable

The central tXtFL class. Starts, perpetuates, and closes the game. The game start calls the teams, sets up the number of players, and hands over control to the game model. The game model solicits user play choices, generates computer moves, and creates the random component of each play's results. After perpetuating plays until the clock runs out, the game model transfers control to the end game, which displays and writes game, season, and team statistics.
