  24: **  READCF -- read control file.
  25: **
  26: **	This routine reads the control file and builds the internal
  27: **	form.
  28: **
  29: **	The file is formatted as a sequence of lines, each taken
  30: **	atomically.  The first character of each line describes how
  31: **	the line is to be interpreted.  The lines are:
  32: **		Dxval		Define macro x to have value val.
  33: **		Cxword		Put word into class x.
  34: **		Fxfile [fmt]	Read file for lines to put into
  35: **				class x.  Use scanf string 'fmt'
  36: **				or "%s" if not present.  Fmt should
  37: **				only produce one string-valued result.
  38: **		Hname: value	Define header with field-name 'name'
  39: **				and value as specified; this will be
  40: **				macro expanded immediately before
  41: **				use.
  42: **		Sn		Use rewriting set n.
  43: **		Rlhs rhs	Rewrite addresses that match lhs to
  44: **				be rhs.
  45: **		Mn arg=val...	Define mailer.  n is the internal name.
  46: **				Args specify mailer parameters.
  47: **		Oxvalue		Set option x to value.
  48: **		Pname=value	Set precedence name to value.
  49: **
  50: **	Parameters:
  51: **		cfname -- control file name.
  52: **
  53: **	Returns:
  54: **		none.
  55: **
  56: **	Side Effects:
  57: **		Builds several internal tables.
