Use the "howto" document class rather than the "manual" class.

Remove the module index; there aren't enough modules documented yet
for this to make sense.

Add a couple more index entries, fixed a few typos, and adjusted a few
more things for consistency.

+\section{Python Abstract Syntax}
 
 The \module{compiler.ast} module defines an abstract syntax for
 Python.  In the abstract syntax tree, each node represents a syntactic
 construct.  The root of the tree is \class{Module} object.
 
 The abstract syntax offers a higher level interface to parsed Python
-source code.  The \module{parser} module and the compiler written in C
-for the Python interpreter use a concrete syntax tree.  The concrete
-syntax is tied closely to the grammar description used for the Python
-parser.  Instead of a single node for a construct, there are often
-several levels of nested nodes that are introduced by Python's
-precedence rules.

 The abstract syntax tree is created by the
 \module{compiler.transformer} module.  The transformer relies on the
 builtin Python parser to generate a concrete syntax tree.  It
 generates an abstract syntax tree from the concrete tree.
