+.PP
+The \fB::struct::queue\fR command creates a new queue object with an

+may be used to invoke various operations on the queue.  It has the

+\fIOption\fR and the \fIarg\fRs

+commands are possible for queue objects:
+.TP
+\fIqueueName \fBclear\fR
+Remove all items from the queue.
+.TP
+\fIqueueName \fBdestroy\fR
+Destroy the queue, including its storage space and associated command.
+.TP
+\fIqueueName \fBget\fR ?\fIcount\fR?
+Return the front \fIcount\fR items of the queue and remove them
+from the queue.  If \fIcount\fR is not specified, it defaults to 1.
+If \fIcount\fR is 1, the result is a simple string; otherwise, it is a list.
+If specified, \fIcount\fR must be greater than or equal to 1.  If
+there are no items in the queue, this command will return \fIcount\fR
+empty strings.
+.TP
+\fIqueueName \fBpeek\fR ?\fIcount\fR?
+Return the front \fIcount\fR items of the queue, without removing them

+.TP
+\fIqueueName \fBput\fR \fIitem\fR ?\fIitem ...\fR?
+Put the item or items specified into the queue.  If more than one
+item is given, they will be added in the order they are listed.

+.PP
+The \fB::struct::tree\fR command creates a new tree object with an
+associated global Tcl command whose name is \fItreeName\fR.  This command
+may be used to invoke various operations on the tree.  It has the
+following general form:
+.CS
+\fItreeName option \fR?\fIarg arg ...\fR?
+.CE
+\fIOption\fR and the \fIarg\fRs
+determine the exact behavior of the command.  The following
+commands are possible for tree objects:
+.TP
+\fItreeName \fBclear\fR
+Remove all nodes from the tree.
+.TP
+\fItreeName \fBdestroy\fR
+Destroy the tree, including its storage space and associated command.
+.TP
+\fItreeName \fBinsert\fR \fIindex\fR \fIparent\fR \fIchild\fR ?-value \fIvalue\fR?
+Insert a node named \fIchild\fR into the tree as a child of the node
+\fIparent\fR.  If \fIparent\fR is \fBroot\fR, it refers to the root of
+the tree.  The new node will have the value given by \fIvalue\fR.  The
+new node will be added to the \fIparent\fR node's childlist at the
+index given by \fIindex\fR.
+.TP
+\fItreeName\fR \fBchildren\fR \fInode\fR
+Return a list of the children of \fInode\fR.
+.TP
+\fItreeName\fR \fBparent\fR \fInode\fR
+Return the parent of \fInode\fR.
+.TP
+\fItreeName\fR \fBnodeconfigure\fR \fInode\fR -value \fIvalue\fR
+Set the associated value of a particular node.
+.TP
+\fItreeName\fR \fBnodecget\fR \fInode\fR -value
+Return the associated value of a particular node.
+.TP
+\fItreeName\fR \fBdelete\fR \fInode\fR ?\fInode\fR ...?
+Remove the specified nodes from the tree.  All of the nodes' children
+will be removed as well to prevent orphaned nodes.  An entire tree
+could be removed in this fashion with the command:
+.CS
+\fItreeName\fR \fBdelete\fR [\fItreeName\fR \fBchildren\fR root]
+.CE
+.TP
+\fItreeName\fR \fBmove\fR \fInode\fR \fIparent\fR \fIindex\fR
+Make \fInode\fR a child of \fIparent\fR, inserting it
+into the parent's child list at the index given by \fIindex\fR.
+.TP
+\fItreeName\fR \fBexists\fR \fInode\fR
+Remove true if the specified node exists in the tree.
