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.
