+# ::tk_optionMenu --
+# This procedure creates an option button named $w and an associated
+# menu.  Together they provide the functionality of Motif option menus:
+# they can be used to select one of many values, and the current value
+# appears in the global variable varName, as well as in the text of
+# the option menubutton.  The name of the menu is returned as the
+# procedure's result, so that the caller can use it to change configuration
+# options on the menu or otherwise manipulate it.
+#
+# Arguments:
+# w -			The name to use for the menubutton.
+# varName -		Global variable to hold the currently selected value.
+# firstValue -		First of legal values for option (must be >= 1).
+# args -		Any number of additional values.
