(See also _H_e_l_p files for _r_t, _r_t_t_e_m_p_l_a_t_e and _r_t_l_e_a_r_n.)

Synopsis:  _r_t  _f_i_l_e_n_a_m_e._r_t     or    _r_t  _f_i_l_e_n_a_m_e._r_t &
where _f_i_l_e_n_a_m_e._r_t is the name  of  a  previously  saved  mix
specification (_r_t script) file.

     _r_t_o_p_e_n is a simple script that will launch the  program
and  load  in  the  data  from an existing mix specification
file. _r_t_o_p_e_n looks in your current  working  Unix  directory
(rather  than in your current _s_n_d directory, like _r_t itself)
for this ascii file.
