+"""Identifier renaming module.
+
+This module implements a few functions to rename identifiers according to some
+naming conventions.
+
+Normalize is the main function, allowing to convert an identifier using an
+arbitrary naming convention into another naming convention. For example:
+
+naming.Normalize("MyIdentifier", naming.Upper) will return "MY_IDENTIFIER".
+
+When the same identifier has to be converted into several conventions, it is
+more efficient to use SplitWords once, and call the conversion functions
+directly:
+
+words = naming.SplitWords("MyIdentifier")
+print naming.Upper(words)
+-> MY_IDENTIFIER
+print naming.Lower(words)
+-> my_identifier
+print naming.LowerTrailing(words)
+-> my_identifier_
+print naming.Java(words)
+-> myIdentifier
+print naming.Capitalized(words)
+-> MyIdentifier
+"""
