/* Frozen modules initializer
*
* Frozen modules are written to header files by Programs/_freeze_module.
* These files are typically put in Python/frozen_modules/. Each holds
* an array of bytes named "_Py_M__<module>", which is used below.
*
* These files must be regenerated any time the corresponding .pyc
* file would change (including with changes to the compiler, bytecode
* format, marshal format). This can be done with "make regen-frozen".
* That make target just runs Tools/build/freeze_modules.py.
*
* The freeze_modules.py script also determines which modules get
* frozen. Update the list at the top of the script to add, remove,
* or modify the target modules. Then run the script
* (or run "make regen-frozen").
*
* The script does the following:
*
* 1. run Programs/_freeze_module on the target modules
* 2. update the includes and _PyImport_FrozenModules[] in this file
* 3. update the FROZEN_FILES variable in Makefile.pre.in
* 4. update the per-module targets in Makefile.pre.in
* 5. update the lists of modules in PCbuild/_freeze_module.vcxproj and
* PCbuild/_freeze_module.vcxproj.filters
*
* (Note that most of the data in this file is auto-generated by the script.)
*
* Those steps can also be done manually, though this is not recommended.
* Expect such manual changes to be removed the next time
* freeze_modules.py runs.
* */
/* In order to test the support for frozen modules, by default we
define some simple frozen modules: __hello__, __phello__ (a package),
and __phello__.spam. Loading any will print some famous words... */
