+This is gxditview, an X11 previewer for groff based on MIT's xditview.
+This version can be used with the output of gtroff -Tps as well as
+with -TX75 and -TX100.  You will need X11R5 or newer to install it (it
+might work on X11R4, but I haven't tested it.)
+
+Previously, gxditview were installed in the usual place for X binaries
+(e.g., /usr/bin/X11); you have to remove it manually.
+
+xditview is copyrighted by MIT under the usual X terms (see
+gxditview.man); the changes to that come along with the groff package
+are in the public domain.
+
+Please report bugs to bug-groff@gnu.org.

+.TH GXDITVIEW 1 "Release 5" "X Version 11"
+.SH NAME
+gxditview \- display gtroff output files
+.SH SYNOPSIS
+.B gxditview
+.RI [\fB\- toolkitoption\  .\|.\|.\|]
+.RI [\fB\- option\  .\|.\|.\|]
+.RI [ filename ]
+.SH DESCRIPTION
+The
+.I gxditview 
+program displays gtroff output on an X display.
+It uses the standard X11 fonts,
+so it does not require access to the server machine for font loading.
+.PP
+If
+.I filename
+is
+.BR \- ,
+.I gxditview
+will read the standard input.
+.PP
+The left mouse button brings up a menu with the following entries:
+.TP 8
+.B "Next Page"
+Display the next page.
+.TP
+.B "Previous Page"
+Display the previous page.
+.TP
+.B "Select Page"
+Select a particular numbered page specified by a dialog box.
+.TP
+.B Print
+Print the gtroff output using a command specified by a dialog box.
+The default command initially displayed is controlled by the
+.B printCommand
+application resource, and by the
+.B \-printCommand
+option.
+.TP
+.B Open
+Open for display a new file specified by a dialog box.
+The file should contain gtroff output.
+If the filename starts with
+.B |
+it will be taken to be a command to read from.
+.TP
+.B Quit
+Exit from
+.IR gxditview .
+.PP
+The
+.BR n ,
+Space
+and Return keys are bound to the
+.B Next\ Page
+action.
+The
+.BR p ,
+BackSpace
+and
+Delete
+keys are bound to the
+.B Previous\ Page
+action.
+The
+.B q
+key is bound to the
+.B Quit
+action.
+The
+.B r
+key is bound to the
+.B Rerasterize
+action which rereads the current file, and redisplays the current page;
+if the current file is a command, the command will be reexecuted.
+.PP
+The
+.B paperlength
+and
+.B paperwidth
+commands in the DESC file specify the length and width in machine units
+of the virtual page displayed by
+.IR gxditview .
+.SH OPTIONS
+.I Gxditview
+accepts all of the standard X Toolkit command line options along with the 
+additional options listed below:
+.TP 8
+.B \-help
+This option indicates that a brief summary of the allowed options should be
+printed.
+.TP
+.B \-page
+This option specifies the page number of the document to be displayed.
+.TP
+.BI \-backingStore\  backing-store-type
+Redisplay of the gtroff output window can take upto a second or so,
+this option causes the server to save the window contents so that when
+it is scrolled around the viewport, the window is painted from
+contents saved in backing store.
+.I backing-store-type
+can be one of
+.BR Always ,
+.B WhenMapped
+or 
+.BR NotUseful .
+.TP
+.BI \-printCommand\  command
+The default command displayed in the dialog box for the
+.B Print
+menu entry will be
+.IR command .
+.TP
+.BI \-resolution\  res
+The gtroff output file will be displayed at a resolution of
+.I res
+dpi,
+unless the DESC file contains the
+.B X11
+command, in which case the device resolution will be used.
+This corresponds the
+.I Dvi
+widget's
+.B resolution
+resource.
+The default is 75.
+.TP
+.BI \-filename\  string
+The default filename displayed in the dialog box for the
+.B Open
+menu entry will be
+.IR string .
+This can be either a filename, or a command starting with
+.BR | .
+.PP
+The following standard X Toolkit command line arguments are commonly used with 
+.IR gxditview :
+.TP 8
+.BI \-bg\  color
+This option specifies the color to use for the background of the window.  
+The default is \fIwhite\fP.
+.TP
+.BI \-bd\  color
+This option specifies the color to use for the border of the window.
+The default is \fIblack\fP.
+.TP
+.BI \-bw\  number
+This option specifies the width in pixels of the border surrounding the window.
+.TP
+.BI \-fg\  color
+This option specifies the color to use for displaying text.  The default is 
+\fIblack\fP.
+.TP
+.BI \-fn\  font
+This option specifies the font to be used for displaying widget text.  The
+default is \fIfixed\fP.
+.TP
+.B \-rv
+This option indicates that reverse video should be simulated by swapping
+the foreground and background colors.
+.TP
+.BI \-geometry\  geometry
+This option specifies the preferred size and position of the window.
+.TP
+.BI \-display\  host : display
+This option specifies the X server to contact.
+.TP
+.BI \-xrm\  resourcestring
+This option specifies a resource string to be used.
+.SH X DEFAULTS
+This program uses the 
+.I Dvi
+widget in the X Toolkit.  It understands all of the core resource names and
+classes as well as:
+.PP
+.TP 8
+.BR width\  (class\  Width )
+Specifies the width of the window.
+.TP
+.BR height\  (class\  Height )
+Specifies the height of the window.
+.TP
+.BR foreground\  (class\  Foreground )
+Specifies the default foreground color.
+.TP
+.BR font\  (class\  Font )
+Specifies the font to be used for error messages.
+.TP
+.BR fontMap\  (class\  FontMap )
+Specifies the mapping from groff font names to X font names.  This
+must be a string containing a sequence of lines.  Each line contains
+two whitespace separated fields: first the groff font name, and
+secondly the X font name.  The default is
+.nf
