+// This is a sample mel script to flag a Maya node with one, two, or
+// three eggObjectTypes* attributes.  These attributes are used to tag
+// geometry with special meaning to Panda.  There are a handful of
+// attribute values that are predefined within Panda, but you can also
+// make up your own attribute values, and define an arbitrary egg
+// syntax to associate with each one.
+//
+// Each type you invoke this script to add an attribute to a node, it
+// adds a new pull-down menu on the node attributes list, giving all
+// of the values listed in $eggFlags, below.  You can then select one
+// of these values to assign to the node.  If you need to assign
+// multiple different values to the same node, run this script
+// multiple times.
+//
+// The maya2egg converter will look for eggObjectTypes* attributes and
+// insert the line "<ObjectType> { value }" for each one found, where
+// "value" is the particular value you have selected from the
+// pull-down menu.  Eventually, when the egg loader loads the egg file
+// into Panda (either by loading the egg file interactively into a
+// Panda session, or via an egg2bam command), the <ObjectType> line
+// will be replaced with arbitrary egg syntax defined by your
+// Config.prc file with a line like this:
+//
+//   egg-object-type-value  [your egg syntax here]
+//
+// See panda/src/configfiles/panda.prc.pp and
+// direct/src/configfiles/direct.prc.pp for examples of this.
