       Various programs dealing with word classes use this format
       to define the posssible expansions of  classes  and  their
       respective  probabilities.   Each  expansion  appears on a
       separate line as in the synopsis, where _c_l_a_s_s names a word
       class,  _p  gives  the probability for the class expansion,
       and _w_o_r_d_1 _w_o_r_d_2 _._._.  defines  the  word  string  that  the
       class  expands to.  If _p is omitted it is assumed to be 1.
       (All expansion probabilities for a given class should  sum
       to  one,  although this is not necessarily enforced by the
       software and would lead to improper models.)

       Note that the concept of word class here is generalized to
       include  ``multi-words'',  or  phrases  consisting of more
       than one word.  All expansions  must  have  at  least  one
       word.   Certain  models might impose more restrictive for-
       mats.
