_D_e_p_r_e_c_a_t_e_d:  _S_e_s_s_i_o_n _D_a_t_a _a_n_d _D_e_b_u_g_g_i_n_g _T_o_o_l_s

_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     The functions `traceOn' and `traceOff' have been replaced by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.

     the equivalent functions.
