     The following options can be specified:

     ----AAAA   When this option is specified the width of the output
	  will always be small enough to fit on an A4 page.

     ----bbbb   Default the logical signals from a ".res" file will
	  plotted.  When the option -b is given, bounding
	  waveforms from a ".plt" will plotted.

     ----hhhh   When this option is specified the time axis will be in
	  a horizontal direction (not available when making a
	  plot file for an hp2934 printer).

     ----pppp   When this option is specified the plot file generated
	  will be according to the PIC language, so that it can
	  be included in an PIC/TROFF source text.  Default, a
	  plot file for an hp2934 printer will be generated.

     ----xxxx   When this option is specified the plot file be accord-
	  ing the format as described by _p_l_o_t_f_i_l_e(_3_I_C_D).

     ----rrrr   A right time axis is printed.

     ----nnnn   The left time axis is not printed.

     ----llll length
	  Specifies the length of the time axis in cm.

     ----ssss scale
	  Specifies how much time is represented by 1 cm on the
	  time axis.

     ----ttttbbbb t_begin
	  Specifies the begin time of the plot (default: 0).

     ----tttteeee t_end
	  Specifies the end time of the plot (default: the time
	  of the last signal change).

     ----wwww s_width
	  Specifies the width of the signals in cm. (default: 0.4
	  cm for logical signals and 2.0 cm for bounding
	  waveforms).

     The time values (scale, t_begin, t_end) are in seconds, and
     may be specified as floating point or integer.  The follow-
     ing trailing time units may be added to this values: 'm'
     (1e-3), 'u' (1e-6), 'n' (1e-9), or 'p' (1e-12).

     _L_p_s_i_g is a program which can be used to plot signals as a
     function of time.	The signals for example are the simula-
     tion results of the switch-level simulator _s_l_s. The output
     file generated by _l_p_s_i_g must be send to an hp2934 line
     printer (file "_s_i_g_n_a_l_s.lp"), can be included in a PIC/TROFF
     source text (file "_s_i_g_n_a_l_s.pic"), or can be used with _h_p_n_e_w
     or _q_p_l_o_t (file "plotfile").  The scaling of the plot can be
     controlled by either the scale option or the length option.
     When none of these options is specified the plot will be
     scaled in such a way that it fits on one page.

     The following program argument is required:

     - _s_i_g_n_a_l_s.     This name must be the basename of a file with
		    the extension ".res" or the basename of a
		    file with the extension ".plt".  The file
		    respectively contains descriptions of logical
		    signals or waveform signals, and is for exam-
		    ple generated by _s_l_s.
