Usage:  renfont  widfile.WID  "oldname"  "newname"

 will rename the typeface "oldname" to "newname" in the specified
 Ventura Publisher .WID file.  Typeface names are case-specific.  They
 must be enclosed in double quotes if they contain any space characters,
 and each must be less than 32 characters long--for many width tables,
 the limit is actually 15.  If you try to use a name that is too long
 for your width file structure, RENFONT will stop and complain rather
 than do any violence to the file.

 This program directly alters the specified .WID file.  If you're not
 sure what you're doing, make a backup copy of your width file first!
