+.SH NAME
+viewres - graphical class browser for Xt
+.SH SYNOPSIS
+.B "viewres"
+[-option ...]
+.SH DESCRIPTION
+.PP
+The \fIviewres\fP program displays a tree showing the widget class hierarchy of
+the Athena Widget Set.  Each node in the tree can be expanded to show the
+resources that the corresponding class adds (i.e. does not inherit from its
+parent) when a widget is created.  This application allows the user to visually
+examine the structure and inherited resources for the Athena Widget Set.
+.SH OPTIONS
+\fIViewres\fP accepts all of the standard toolkit command line options as
+well as the following:
+.TP 8
+.B \-top \fIname\fP
+This option specifies the name of the highest widget in the hierarchy to 
+display.  This is typically used to limit the display to a subset of the
+tree.  The default is \fIObject\fP.
+.TP 8
+.B \-variable
+This option indicates that the widget variable names (as declared in 
+header files) should be displayed in the nodes rather than the widget
+class name.  This is sometimes useful to distinguish widget classes that
+share the same name (such as \fIText\fP).
+.TP 8
+.B \-vertical
+This option indicates that the tree should be displayed top to bottom
+rather left to right.
+.SH "VIEW MENU"
+The way in which the tree is displayed may be changed through the 
+entries in the \fBView\fP menu:
+.TP 8
+.B "Show Variable Names"
+This entry causes the node labels to be set to the variable names used
+to declare the corresponding widget class.  This operation may also be 
+performed with the \fBSetLabelType(variable)\fP translation.
+.TP 8
+.B "Show Class Names"
+This entry causes the node labels to be set to the class names used when
+specifying resources.  This operation may also be performed with the
+\fBSetLabelType(class)\fP translation.
+.TP 8
+.B "Layout Horizontal"
+This entry causes the tree to be laid out from left to right.  This operation
+may also be performed with the \fISetOrientation(West)\fP translation.
+.TP 8
+.B "Layout Vertical"
+This entry causes the tree to be laid out from top to bottom.  This operation
+may also be performed with the \fISetOrientation(North)\fP translation.
+.TP 8
+.B "Show Resource Boxes"
+This entry expands the selected nodes (see next section) to show the 
+new widget and constraint resources.  This operation
+may also be performed with the \fIResources(on)\fP translation.
+.TP 8
+.B "Hide Resource Boxes"
+This entry removes the resource displays from the selected nodes (usually to
+conserve space).  This operation
+may also be performed with the \fIResources(off)\fP translation.
+.SH "SELECT MENU"
+Resources for a single widget class can be displayed by clicking
+\fBButton2\fP on the corresponding node, or by adding the node to the
+selection list with \fBButton1\fP and using the \fBShow Resource Boxes\fP
+entry in the \fBView\fP menu.  Since \fBButton1\fP actually toggles the
+selection state of a node, clicking on a selected node will cause it to be
+removed from the selected list.
+.PP
+Collections of nodes may also be selected through the various entries in
+the \fBSelect\fP menu:
+.TP 8
+.B "Unselect All"
+This entry removes all nodes from the selection list.  This operation
+may also be performed with the \fISelect(nothing)\fP translation.
+.TP 8
+.B "Select All"
+This entry adds all nodes to the selection list.  This operation
+may also be performed with the \fISelect(all)\fP translation.
+.TP 8
+.B "Invert All"
+This entry adds unselected nodes to, and removes selected nodes from, the
+selection list.  This operation
+may also be performed with the \fISelect(invert)\fP translation.
+.TP 8
+.B "Select Parent"
+This entry selects the immediate parents of all selected nodes.  This operation
+may also be performed with the \fISelect(parent)\fP translation.
+.TP 8
+.B "Select Ancestors"
+This entry recursively selects all parents of all selected nodes.  This 
+operation may also be performed with the \fISelect(ancestors)\fP translation.
+.TP 8
+.B "Select Children"
+This entry selects the immediate children of all selected nodes.  This 
+operation may also be performed with the \fISelect(children)\fP translation.
+.TP 8
+.B "Select Descendants"
+This entry recursively selects all children of all selected nodes.  This 
+operation may also be performed with the \fISelect(descendants)\fP translation.
+.TP 8
+.B "Select Has Resources"
+This entry selects all nodes that add new resources (regular or constraint)
+to their corresponding widget classes.  This operation
+may also be performed with the \fISelect(resources)\fP translation.
+.TP 8
+.B "Select Shown Resource Boxes"
+This entry selects all nodes whose resource boxes are currently expanded
+(usually so that they can be closed with \fBHide Resource Boxes\fP).  This 
+operation may also be performed with the \fISelect(shown)\fP translation.
+.SH "ACTIONS"
+The following application actions are provided:
+.TP 8
+.B "Quit()"
+.br
+This action causes \fIviewres\fP to exit.
+.TP 8
+.B "SetLabelType(\fItype\fP)"
+This action sets the node labels to display the widget \fIvariable\fP or 
+\fIclass\fP names, according to the argument \fItype\fP.
+.TP 8
+.B "SetOrientation(\fIdirection\fP)"
+This action sets the root of the tree to be one of the following areas of
+the window:  \fIWest\fP, \fINorth\fP, \fIEast\fP, or \fISouth\fP.
+.TP 8
+.B "Select(\fIwhat\fP)"
+This action selects the indicated nodes, as described in the \fBVIEW MENU\fP
+section: \fInothing\fP (unselects all nodes), \fIinvert\fP, \fIparent\fP,
+\fIancestors\fP, \fIchildren\fP, \fIdescendants\fP, \fIresources\fP, 
+\fIshown\fP.
+.TP 8
+.B "Resources(\fIop\fP)"
+This action turns \fIon\fP, \fIoff\fP, or \fItoggles\fP the resource boxes
+for the selected nodes.
+If invoked from within one of the nodes (through the keyboard or pointer),
+only that node is used.
+.SH "WIDGET HIERARCHY"
+Resources may be specified for the following widgets:
