//  This is a private header file for twhile.c, tttfield.c, tttitem.c and ttt.c.  The file format
//  that it reads was formerly called "Twistory Text Type" and had the faux extension .ttt, although
//  they were always TEXT files.  Now with extentions being meaningful in OS X, the extension is just .txt.
