Usage:  IDCHECK  widfile1 widfile2

 will check the two specified Ventura Publisher .WID files to see
 whether any conflicts exist in their use of typeface ID numbers.
 Any such conflicts are reported, and the user is given the option of
 changing the font ID in the second file to obviate each conflict.
 If the user chooses a substitute ID that is already used in either
 file, IDCHECK will prompt the user for another number.
