+ast
+~~~
+
+The `ast` module helps Python applications to process trees of the Python
+abstract syntax grammar.  The abstract syntax itself might change with
+each Python release; this module helps to find out programmatically what
+the current grammar looks like and allows modifications of it.
+
+An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
+a flag to the `compile()` builtin function or by using the `parse()`
+function from this module.  The result will be a tree of objects whose
+classes all inherit from `ast.AST`.
+
+A modified abstract syntax tree can be compiled into a Python code object
+using the built-in `compile()` function.
+
+Additionally various helper functions are provided that make working with
+the trees simpler.  The main intention of the helper functions and this
+module in general is to provide an easy to use interface for libraries
+that work tightly with the python syntax (template engines for example).
