# This function now implements Python byte-compilation in two different ways:
# Python >= 3.4 uses a new module compileall2 - https://github.com/fedora-python/compileall2
# This function now implements Python byte-compilation in three different ways:
# Python >= 3.4 and < 3.9 uses a new module compileall2 - https://github.com/fedora-python/compileall2
# Python < 3.4 (inc. Python 2) uses compileall module from stdlib with some hacks
# When we drop support for Python 2, we'd be able to use all compileall2 features like:
# - -s and -p options to manipulate with a path baked into pyc files instead of $real_libdir
# - -o 0 -o 1 to produce multiple files in one run - each with a different optimization level - instead of $options
# - removed useless $depth - both compileall and compileall2 are limited by sys.getrecursionlimit()
# These changes will make this script much simpler
# In Python >= 3.9, compileall2 was merged back to standard library (compileall) so we can use it directly again.
