/* 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/scripts/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.
 * */
