_D_e_s_c_r_i_p_t_i_o_n:

     The functions 'traceOn' and 'traceOff' have been replaced by
     extended versions of the functions 'trace' and 'untrace', and
     should not be used.

_U_s_a_g_e:

     sessionData()

     traceOn(what, tracer=browseAll, exit=NULL)

     traceOff(what)

     browseAll()

_D_e_t_a_i_l_s:


     '_s_e_s_s_i_o_n_D_a_t_a': return the index of the session data in the search
          list, attaching it if it is not attached.


     '_t_r_a_c_e_O_n': initialize tracing on calls to function 'what'.  The
          function or expression 'tracer' is called on entry, and the
          function or expression 'exit' on exit.


     '_t_r_a_c_e_O_f_f': turn off tracing of this function.


     '_b_r_o_w_s_e_A_l_l': browse the current stack of function calls.

          Uses the function 'debugger' to set up browser calls on the
          frames.  On exit from that function, computation continues
          after the call to 'browseAll'.  Computations done in the
          frames will have no effect.
