Is the new and empty tools/configure_lib/__init__.py necessary?

tools/configure_lib/nodedownload.py
try:
from urllib.request import FancyURLopener

Is the new and empty tools/configure_lib/__init__.py necessary?

It's a python thing (it tells the runtime that that directory is a "package") that enables doing:
https://github.com/nodejs/node/blob/aa3826ae54ee2422ffc38ca1b94e8dea7f09de8c/configure.py#L25
instead of:

node/configure.py

Lines 30 to 32 in 2fa8dc4

# imports in tools/configure.d
sys.path.insert(0, os.path.join('tools', 'configure.d'))
import nodedownload

(which is not cricket)

This is not necessary for Python 3 compatibility I believe. Can you explain why this is introduced?

configure.py
parser = argparse.ArgumentParser()
shared_optgroup = parser.add_argument_group(
"Shared libraries",
"Flags that allows you to control whether you want to build against built-in dependencies"

Nit: There are a few lines which cross the 80 characters limit.

I feel that the refactoring can be done in a separate PR. Not introducing any new additional code would be easy for us to debug problems.

My vote would be that we close this. We have touched these files in the interim and most of these changes have been done. Is there anything remaining that we should consider?
