-# This file describes the nodes of the AST in ast.py.  The module is
-# generated by astgen.py.  
-# The descriptions use the following special notation to describe
-# properties of the children:
-#    *   this child is not a node
-#    !   this child is a sequence that contains nodes in it
-#    &   this child may be set to None
-#  = ... a default value for the node constructor (optional args)
