+"""Package for parsing and compiling Python source code
+
+There are several functions defined at the top level that are imported
+from modules contained in the package.
+
+parse(buf, mode="exec") -> AST
+    Converts a string containing Python source code to an abstract
+    syntax tree (AST).  The AST is defined in compiler.ast.
+
+parseFile(path) -> AST
+    The same as parse(open(path))
+
+walk(ast, visitor, verbose=None)
+    Does a pre-order walk over the ast using the visitor instance.
+    See compiler.visitor for details.
+
+compile(source, filename, mode, flags=None, dont_inherit=None)
+    Returns a code object.  A replacement for the builtin compile() function.
+
+compileFile(filename)
+    Generates a .pyc file by compiling filename.
