4084 7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	11 * This module serves to replace the original parser module written
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	12 * by Guido. The functionality is not matched precisely, but the
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	13 * original may be implemented on top of this. This is desirable
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	14 * since the source of the text to be parsed is now divorced from
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	15 * this interface.
3200 8f5ab1a6c914 Fred Drake's new parser module Guido van Rossum <guido@python.org> parents: 2150 diff changeset	16 *
4084 7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	17 * Unlike the prior interface, the ability to give a parse tree
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	18 * produced by Python code as a tuple to the compiler is enabled by
7f83e24d1d86 New batch from Fred Guido van Rossum <guido@python.org> parents: 3774 diff changeset	19 * this module. See the documentation for more details.

885de49b445c Made lint a bit happier. Fred Drake <fdrake@acm.org> parents: 8184 diff changeset	21 * I've added some annotations that help with the lint code-checking

885de49b445c Made lint a bit happier. Fred Drake <fdrake@acm.org> parents: 8184 diff changeset	24 * Py_[X]DECREF() and Py_[X]INCREF() macros. The lint annotations
885de49b445c Made lint a bit happier. Fred Drake <fdrake@acm.org> parents: 8184 diff changeset	25 * look like "NOTE(...)".
