-r"""Utilities to compile possibly incomplete Python source code.
-
-This module provides two interfaces, broadly similar to the builtin
-function compile(), which take program text, a filename and a 'mode'
-and:
-
-- Return code object if the command is complete and valid
-- Return None if the command is incomplete
-- Raise SyntaxError, ValueError or OverflowError if the command is a
-  syntax error (OverflowError and ValueError can be produced by
-  malformed literals).
-
-The two interfaces are:
-
-compile_command(source, filename, symbol):
-
-    Compiles a single command in the manner described above.
-
-CommandCompiler():
-
-    Instances of this class have __call__ methods identical in
-    signature to compile_command; the difference is that if the
-    instance compiles program text containing a __future__ statement,
-    the instance 'remembers' and compiles all subsequent program texts
-    with the statement in force.
-
-The module also provides another class:
-
-Compile():
-
-    Instances of this class act like the built-in function compile,
-    but with 'memory' in the sense described above.
