I wanted this at first as well, but as you already noticed, Python does not
make "import ../" very easy. And then Geoff and others convinced me that
you don't want non-public files in your context. I agree and follow this
style on all my sites:
appone/
pages/
__init__.py
Main.py
Help.html
lib/
__init__.py
SitePage.py
So then I do:
from lib.SitePage import SitePage
This means no one can try to hack my site by running non-servlets or
abstract servlets out of my context.
In the context's __init__.py I have to augment sys.path to know where lib
is. This is something like:
path = os.path.dirname(os.path.dirname(path))
if path not in sys.path:
sys.path.insert(1, path)
You might have to fiddle with that a little, but you get the idea.
In my example, lib/ is under appone/ because I don't share very much
between my apps (that isn't already in Webware). Obviously you could do it
like this:
lib/
appone/
context/
apptwo/
context/
I often have other directories under my apps, like middle/ for MiddleKit
objects, configs/ for config files, fragments/ for html fragements that get
picked up by my servlets, and tests/ for regression test cases.

No, it shouldn't be. If there is, then it would be a bug.
