     _d_p_r_i_m_e can be given two arguments: the hit-rate and the
     false-alarm-rate, for which it will print d' and beta.
     Alternatively, _d_p_r_i_m_e reads raw data from a named file, or
     from the standard input.  If raw data are input, _d_p_r_i_m_e
     assumes a two column input in which the first column tells
     whether signal+noise or just noise were presented, and the
     second column tells how the observer responded.  The follow-
     ing strings can be used to indicate signal+noise:
          signal, yes, 1, 1.0000
     while the following can be used to indicate noise:
          noise, no, 0, 0.0000
