1# This file describes the nodes of the AST in ast.py.  The module is
2# generated by astgen.py.
3# The descriptions use the following special notation to describe
4# properties of the children:
5#    *   this child is not a node
6#    !   this child is a sequence that contains nodes in it
7#    &   this child may be set to None
8#  = ... a default value for the node constructor (optional args)
9#
10# If you add node types here, please be sure to update the list of
11# Node types in Doc/lib/asttable.tex.
