Okay, with your help I've figured it out. Instructions are below, but
read the caveat by Ben Fenny in this thread. All this stuff is good for
one default version of Python only. The PYTHONPATH described below, for
example, cannot specify a version number. Yes, that's a pain in the
butt, but there's no way around it. If you switch versions, you may
have to delete all the .pyc files that will show up in the module
folders. Python ought to check them to see if they are valid, but I do
not know if it does so.
These instructions are for MS Windows.
1) Create your modules folder. Let's say it's named "Modules." The
documentation calls it a "package."
2) In an explorer window or on the desktop, right click on My Computer,
and select Properties.
3) Select the Advanced tab, and click on Environment Variables near the
4) Look for an environment variable named PYTHONPATH.
a) If you do not find one, create one using the New button(s). I
don't know if it has to be in User Variables or System Variables. To
save time experimenting, I just put one in both. For the value, put the
full path of the folder Modules.
b) If there's already a PYTHONPATH, Edit it, adding a semi-colon
and the full path of folder Module to the end.
5) Put your module folders into the folder Module.
6) (Here's a really arcane bit.) Into each module folder, put a file
named __init__.py. It will be executed when you load the module. It
can be empty, but it has to be there or else the module folder will be
