# Defines the AST Node classes used in pycparser.

# Each entry is a Node sub-class name, listing the attributes
# and child nodes of the class:
# <name>* - a child node
# <name>** - a sequence of child nodes
# <name> - an attribute

# ArrayDecl is a nested declaration of an array with the given type.

# dim_quals: list of dimension qualifiers, to support C99's allowing 'const'
# and 'static' within the array dimension in function declarations.
