  This program was written for Robocup2000 in Melbourne.
 
  It reads the record.log created by the server and extracts the two
  team names and the final(?) score. Printing the out in the format:

  <team 1> <team1 goals> <team2> <team2 goals>

  Compile with:
  gcc -Wall -O2 exteamname.c -o exteamname
