  6. PROGRAM:
  7.     ENTAB - Convert runs of spaces to tabs.
  8. USAGE:
  9.     ENTAB [<fid] [>fid]
  10. FUNCTION:
  11.     This copies input to output, replacing strings of spaces by 
  12.     tabs so that the result is visualy the same as the input.
  13.     Tab stops are assumed to occur every 8 characters.
  14. EXAMPLE:
  15.     ENTAB <BIGFILE >LTLFILE
  16. BUGS:
  17.     ENTAB is naive about vertical motion non-printing characters.  
  18.     ENTAB will convert a single blank to a tab if it occurs at 
  19.     a tab stop.  Thus it is not the exact inverse of DETAB.
