It doesn't contain the code as source - it contains it as a decorated 
abstract syntax tree, as produced by the parser.

If you walk this tree you will find first definition nodes, which define 
things. These are chained together using the "chan" key value pair.

There are various types of node:

identifier_node, string_cst, integer_cst and const_decl all define 
constants of one sort or another. Their key/value pairs will describe 
the constant, i.e. it's name, what the constant is, what type it is (if 
applicable), &c.

type_decl, void_type, integer_type, real_type, boolean_type, 
enumeral_type, pointer_type, reference_type, array_type, record_type, 
union_type, function_type and method_type define types. Their key/value 
pairs will indicate their name, size, width, alignment, what type they 
point/refer/are an array of, a link to a tree_list of their member types 
and positions, &c.

var_decl defines a variable, primarily it's name and type.

namespace_decl defines a namespace.

A function_decl node may have a function body attached. This will be 
full of nodes with names ending in _expr. For the purposes of generating 
glue code, this is unneccessary. As such, you'll want to throw them away 
to save memory.

http://www.delorie.com/gnu/docs/gcc/gccint_31.html may help - it's a 
guide to the nodes from the inside, where they're macros, rather than 
from the outside, where they're entries in a file.
