/* 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__", 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.
