The input file format is very simple.  It begins with the 
first line which must be a "league" statement as follows:  

# league NCAAFB

This tells the program what sporting league you are providing 
data for, so the proper set of control variables can be 
applied (more on control variables later).  

Next, every comment line begins with a "# " where the space 
is necessary.  For example:

# this is a legal comment
# NFL data 2008

OK, now comes the most important thing, the Game format.  
Each game is formatted as follows:  

team1 score1 at team2 score2 Vegas_odds

That is for a game where team1 plays at team2's home stadium.  
If the game is played at a neutral site, such as a bowl game 
in NCAAFB, then we use the "vs" keyword as follows:  

team1 score1 vs team2 score2 Vegas_odds

The Vegas_odds are optional.  Games without Vegas_odds 
contribute to the ratings of the two teams, however they do 
not contribute to predictions and predictions will not be 
made for said games.  

If the scores are both minus 1, for example:  

team1 -1 at team2 -1 Vegas_Odds

Then a prediction will be made for that game.  This is how 
the input file requests that the program make a prediction, 
by showing both scores as zero.  

Finally we must adjust the sign of the Vegas_odds.  The 
sportsbooks always show the odds as negatively signed, and 
they display the odds next to either team1 or team2 to 
indicate which team is favored.  The rule is this:  if the 
sportsbook shows the negative odds value by team2, then the 
Vegas_odds is entered as negative.  if, however, the sportsbook 
shows the negative odds value by team1, then the Vegas_odds 
is entered as positive.  This is how the favorite/underdog 
is indicated to the program by the input file.
