+# Tooltip:
+#
+# Caller may call
+# applet::setup-tooltip ON-VISIBLE ON-INVISIBLE
+# to make applet have a tooltip.
+#
+# ON-VISIBLE and ON-INVISIBLE will be globally eval'd
+# when the tooltip becomes visible and invisible.
+#
+# Caller should call
+# applet::tooltip-set TEXT-MAYBE-MULTILINE
+# whenever they like.
+#
+# Inner window subprocess:
+#
+# Caller that needs access to inner window should define
+# proc innerwindow {} { ... }
+# and run
+# innerwindow
+# This will create
+# .i.i.b frame to contain container
+# .i.i.b.c actual container
+#
+# Button presses
+#
+# Caller may bind .i.i <ButtonPress-$b>
+#
+# Alternatively caller may call applet::setup-button-menu $b
+# which will generate a menu .m$b which the user can configure
+# and which will automatically be posted and unposted etc.
