_D_e_s_c_r_i_p_t_i_o_n:

     A (hopefully) simpler alternative interface to
     `trellis.par.get/set'. NOT S-compatible

_U_s_a_g_e:

     lset(theme)
     col.whitebg()

_A_r_g_u_m_e_n_t_s:

   theme: a list decribing how to change the settings of the current
          active device. Valid components are those in the list
          returned by `trellis.par.get()'. Each component must itself
          be a list, with one or more of the appropriate components
          (need not have all components). Changes are made to the
          settings for the currently active device only. 

_D_e_t_a_i_l_s:

     `lset' essentially does the same thing as `trellis.par.set', but
     is different in that it allows setting more than one parameter at
     a time, and also that each component need have only the components
     that need to be changed. 

     This function is expected to be used mostly in conjunction with
     functions that return `themes', i.e., lists which when supplied to
     `lset' change the overall look and feel of the display.

     `col.whitebg' is one such function, which returns a list which
     when supplied to `lset' changes the background to transparent and
     the other colors to something suitable. Contributions of more such
     `themes' are welcome.
