	<brief_description>
		Post-processes scenes after import.
	</brief_description>
	<description>
		Imported scenes can be automatically modified right after import by setting their [b]Custom Script[/b] Import property to a [code]tool[/code] script that inherits from this class.
		The [method post_import] callback receives the imported scene's root node and returns the modified version of the scene. Usage example:
		[codeblock]
		tool # Needed so it runs in editor
		extends EditorScenePostImport

		# This sample changes all node names

		# Called right after the scene is imported and gets the root node
		func post_import(scene):
		    # Change all node names to "modified_[oldnodename]"
		    iterate(scene)
		    return scene # Remember to return the imported scene

		func iterate(node):
		    if node != null:
		        node.name = "modified_" + node.name
		        for child in node.get_children():
		            iterate(child)
		[/codeblock]
