Ok, I tracked it down to distutils.dist. Unfortunately, it looks like
this feature won't be very useful for my use case after all. There are
only a few locations searched for distutils configuration files:
- 'distutils.cfg' must either go inside the distutils package itself
(vendor files, bad)
- '.pydistutils.cfg' ('pydistutils.cfg' in win32/macos classic) located
in the user's home directory (per-user, bad)
- 'setup.cfg' in the current directory (per-package, worse)
I need an editable file in a system-wide directory such as
site-packages that isn't "owned" by the Python installation. Even if
this were the case, it would be a real pain to implement, because it
would have to be done as a very careful postflight script that merges
the user's current config file with the necessary additions (in this
case, make sure to preserve anything else in the command-packages list
if there is one).
