-"""
-This script confirms that the naming of all symbols and identifiers in Mbed TLS
-are consistent with the house style and are also self-consistent. It only runs
-on Linux and macOS since it depends on nm.
-
-It contains two major Python classes, CodeParser and NameChecker. They both have
-a comprehensive "run-all" function (comprehensive_parse() and perform_checks())
-but the individual functions can also be used for specific needs.
-
-CodeParser makes heavy use of regular expressions to parse the code, and is
-dependent on the current code formatting. Many Python C parser libraries require
-preprocessed C code, which means no macro parsing. Compiler tools are also not
-very helpful when we want the exact location in the original source (which
-becomes impossible when e.g. comments are stripped).
-
-NameChecker performs the following checks:
-
-- All exported and available symbols in the library object files, are explicitly
-  declared in the header files. This uses the nm command.
-- All macros, constants, and identifiers (function names, struct names, etc)
-  follow the required regex pattern.
-- Typo checking: All words that begin with MBED|PSA exist as macros or constants.
-
-The script returns 0 on success, 1 on test failure, and 2 if there is a script
-error. It must be run from Mbed TLS root.
