+\chapter{Abstract Syntax Trees\label{ast}}
+
+\sectionauthor{Martin v. L\"owis}{martin@v.loewis.de}
+
+The \code{_ast} module helps Python applications to process
+trees of the Python abstract syntax grammar. The Python compiler
+currently provides read-only access to such trees, meaning that
+applications can only create a tree for a given piece of Python
+source code; generating byte code from a (potentially modified)
+tree is not supported. The abstract syntax itself might change with
+each Python release; this module helps to find out programmatically
+what the current grammar looks like.
+
+An abstract syntax tree can be generated by passing \code{_ast.PyCF_ONLY_AST}
+as a flag to the \function{compile} builtin function. The result will be a tree
+of objects whose classes all inherit from \code{_ast.AST}.
+
+The actual classes are derived from the \code{Parser/Python.asdl} file,
+which is reproduced below. There is one class defined for each left-hand
+side symbol in the abstract grammar (for example, \code{_ast.stmt} or \code{_ast.expr}).
+In addition, there is one class defined for each constructor on the
+right-hand side; these classes inherit from the classes for the left-hand
+side trees. For example, \code{_ast.BinOp} inherits from \code{_ast.expr}.
+For production rules with alternatives (aka "sums"), the left-hand side
+class is abstract: only instances of specific constructor nodes are ever
+created.
+
+Each concrete class has an attribute \code{_fields} which gives the
+names of all child nodes.
+
+Each instance of a concrete class has one attribute for each child node,
+of the type as defined in the grammar. For example, \code{_ast.BinOp}
+instances have an attribute \code{left} of type \code{_ast.expr}.
+
+If these attributes are marked as optional in the grammar (using a
+question mark), the value might be \code{None}. If the attributes
+can have zero-or-more values (marked with an asterisk), the
+values are represented as Python lists.
+
+\subsection{Abstract Grammar}
+
+The abstract grammar is currently defined as follows:
