# This package is part of the Python 3 bootstrapping sequence.
#
# The python3-devel subpackage has a runtime dependency on this package.
# Therefore it needs to be built before Python 3 itself. To facilitate this,
# this package has a bootstrapping mode—triggered by the macro below—that skips
# bytecompilation and therefore no Python is actually needed for building of
# this package. After Python 3 is built, this package can be rebuilt in
# normal mode again.
#
# Note, however, that even the bootstrapping version of this package is fully
# functional as Python will simply bytecompile the Python files when they are
# run. There will be a warning that the bytecompiled file cannot be saved
# (unless Python is run with root privileges), but the script will work.
#
# More info on the Python 3 bootstrapping sequence in the `python3` spec file.

%global bootstrapping_python 0


# Disable automatic (Python 2) bytecompilation in %%__os_install_post.
# When not in bootstrapping mode, the scripts are bytecompiled
# in the %%install section.
