| 9 | This module provides constants which represent the numeric values of |
| 10 | internal nodes of the parse tree. Unlike most Python constants, these |
| 11 | use lower-case names. Refer to the file \file{Grammar/Grammar} in the |
| 12 | Python distribution for the defintions of the names in the context of |
| 13 | the language grammar. The specific numeric values which the names map |
| 14 | to may change between Python versions. |

| 16 | This module also provides one additional data object: |

| 22 | module back to name strings, allowing more human-readable |
| 23 | representation of parse trees to be generated. |
