Oops! I must have had Frame on the brain that day.

Here is the man page from the next release (3.3). I left all the ^H
overstrike stuff in. It should be OK if you run it through ul or use
less to view it.

_p_s_v_i_e_w puts up a window and runs the user's PostScript
code in it.
_p_s_v_i_e_w uses a portion of the window that has the proper
aspect ratio for
a standard letter-size page in portrait orientation.
If _P_o_s_t_S_c_r_i_p_t-_f_i_l_e is specified, the
PostScript code is taken from that
file. If no argument is given, or if a `-' is given as the argument,
_p_s_v_i_e_w reads the PostScript program from standard input.
_p_s_v_i_e_w works best with files obeying the Adobe
_D_o_c_u_m_e_n_t _S_t_r_u_c_t_u_r_i_n_g
_C_o_n_v_e_n_t_i_o_n_s. (Such files contain special
comments such as %%_P_a_g_e:.)
When previewing such a file _p_s_v_i_e_w lets you flip
through the pages with
page boundaries being determined by locating the %%Page: comments.
_p_s_v_i_e_w provides a slider to move to any page, and a
menu to go to the
first, previous, next or last page. Clicking the left mouse button goes
to the next page. If the document has only a single page, neither the
slider nor the page movement menu entries appear.
All commands may be given from the keyboard. Space or '+' goes to the
next page. Backspace or '-' goes to the previous page. '0', '<', or
',' go to the first page. '$', '>', or '.' go to the last page. '^C'
or 'q' cause _p_s_v_i_e_w to exit.
If the file doesn't follow the document structuring conventions, it is
treated as having a single page. If the PostScript program in that file
calls
sssshhhhoooowwwwppppaaaaggggeeee,,,,
_p_s_v_i_e_w will pause. Clicking the left mouse or selecting
the _N_e_x_t _P_a_g_e menu entry will resume output. When
the window is redrawn
in response to damage or to selecting _R_e_d_i_s_p_l_a_y
from the menu, any
pending output is flushed and the program is executed from the beginning
of the file.
The options, which may appear in any order so long as they appear before
the file, are:
----xxxx1111,,,,yyyy1111----xxxx2222,,,,y
yyy2222
Sets the bounding box of the active part of the psview window.
The coordinates are given as floating point values in inches.
----BBBB Normally psview draws a box to show the edges of
the paper. This
stops the box being drawn.

Sets the background color. The default is white. <color spec>
has the syntax [hr]x,y,z where x, y, and z are either floating
point numbers between 0 and 1 or integers between 0 and 255. _h
selects the hsb color model which is the default. _r selects the

rgb color model. An individual color part may be set by, for
example ----bbbb_g_0._5. Changing the background
color may have strange
effects especially if the PostScript file uses color.
----cccc Sets the background to blue and the foreground
to white.
----FFFF<<<<ssssccccaaaalllleeee>>>>
Gives the window a fixed initial size that defaults to the full
height of the screen. _S_c_a_l_e, which defaults to
1.0, applies a
uniform scaling to the default initial size.

Sets the foreground color. <color spec> is the same as for the
background color. Changing the foreground color may have strange
effects especially if the PostScript file uses color.
----llll Makes psview use a portion of the window that
gives the aspect
ratio of a landscape oriented 11 x 7 slide.
----SSSS Makes psview use a portion of the window that
gives the aspect
ratio of a portrait oriented 6.8 x 11 slide.
----ssss Makes psview use a portion of the window that
gives the aspect
ratio of a portrait oriented 5.7 x 11 slide.
