# 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)
#
# If you add node types here, please be sure to update the list of 
# Node types in Doc/lib/asttable.tex.
