+Clang Indexing Library Bindings
+===============================
+
+This module provides an interface to the Clang indexing library. It is a
+low-level interface to the indexing library which attempts to match the Clang
+API directly while also being "pythonic". Notable differences from the C API
+are:
+
+ * string results are returned as Python strings, not CXString objects.
+
+ * null cursors are translated to None.
+
+ * access to child cursors is done via iteration, not visitation.
+
+The major indexing objects are:
+
+  Index
+
+    The top-level object which manages some global library state.
+
+  TranslationUnit
+
+    High-level object encapsulating the AST for a single translation unit. These
+    can be loaded from .ast files or parsed on the fly.
+
+  Cursor
+
+    Generic object for representing a node in the AST.
+
+  SourceRange, SourceLocation, and File
+
+    Objects representing information about the input source.
+
+Most object information is exposed using properties, when the underlying API
+call is efficient.
+"""
+
+# TODO
+# ====
+#
+# o API support for invalid translation units. Currently we can't even get the
+#   diagnostics on failure because they refer to locations in an object that
+#   will have been invalidated.
+#
+# o fix memory management issues (currently client must hold on to index and
+#   translation unit, or risk crashes).
+#
+# o expose code completion APIs.
+#
+# o cleanup ctypes wrapping, would be nice to separate the ctypes details more
+#   clearly, and hide from the external interface (i.e., help(cindex)).
+#
+# o implement additional SourceLocation, SourceRange, and File methods.
