NAME
                                  r
     psview - preview a PostScript  document

SYNOPSIS
     psview [-options...] [option-values ...]

DESCRIPTION
                                         r
     Psview is a simple-minded PostScript  document previewer.
     It interprets the document and displays it, one page at a
     time.  A pop-up menu and mouse button bindings are provided
     to permit paging forward and backward, marking pages and
     printing pages.

     By default, the right mouse button proceeds to the next
     page, the left button returns to the previous page and the
     middle button pops up a menu of other options.  When the
     shift key is held down, the right button proceeds to the
     next marked page, the left button returns to the previous
     marked page, and the middle button marks the current page.
     When the control key is held down, the right button jumps to
     the last page of the document, the left button jumps to the
     first page of the document, and the middle button causes a
     prompt for a page number to be displayed.

OPTIONS
     Psview does not accept the standard X Toolkit command line
     options because it has does not use the X Toolkit (yet).
     Psview uses a non-standard mechanism for specifying command
     line options; a list of flags is given first, followed by a
     list of corresponding values.  For example:

          psview -dhw 300 10.0 7.5

     Psview supports the following options:

     -d      Set the display resolution used for previewer calcu-
             lations to the corresponding value (in dots per
             inch).  By default the previewer uses the highest
             resolution available on the display.

     -g      Set the previewer geometry to the corresponding
             value.  Only the size is used.  By default the pre-
             viewer simulates an 81/2 by 11 inch sheet of paper.

     -h      Set the relative height of the previewer window to
             the corresponding value.  By default the previewer
             simulates an 81/2 by 11 inch sheet of paper.

     -i      Set the "increment interval" to the corresponding
             value.  This value determines how many lines of text
             are read between screen updates.  The default is
             200.

     -l      Tell the previewer to simulate a legal-size sheet of
             paper (81/2 by 14 inch).  By default the previewer
             simulates an 81/2 by 11 inch sheet of paper.

     -R      This option instructs the previewer to perform
             rigorous analysis of the document for Adobe struc-
             ture.  This frequently causes the previewer to
             reject a document that does not sufficiently adhere
             to this structure.  Because the information derived
             from this analysis is required for proper paging
             behavior, this option is true by default.

     -r      This option instructs the previewer not to perform
             rigorous analysis of the document for Adobe struc-
             ture.  This may allow the previewer to display a
             document that would otherwise be rejected.  However,
             without the correct structure, the previewer will
             not have a reasonable concept of pages, so this
             option is only useful for single page documents.
             This option is false by default.

     -s      Set the first page to be displayed to the
             corresponding value.  By default the previewer
             starts at page one.

     -w      Set the relative width of the previewer window to
             the corresponding value.  By default the previewer
             simulates an 81/2 by 11 inch sheet of paper.

BUGS
     Psview was designed originally as a previewer for documents
                               r
     developed under the Scribe  document preparation system and
     frequently rejects documents from other sources.

     Psview is a ported version of an older X10 application and
     as such does not yet use X11 widgets, resources, app-
     defaults, or command line arguments in accordance with stan-
     dard X11 practice.
