  GvR> For Windows, the IDLE problem is solved: it's installed in
  GvR> directory <topdir>/Tools/idle/ and there's a link to it in the

  GvR> Maybe we can extend this idea to Unix.  Concrete proposal:
  GvR> install IDLE as
  GvR> <prefix>/lib/python<version>/site-packages/Tools/idle/, and
  GvR> place a symlink or 2-line bootstrap script in
  GvR> <prefix>/bin/idle.

How about
instead.  I suggest the change to support an until-now-implicit policy
that anything in site-packages actually be a package.  If things in
site-packages aren't supposed to be packages, it ought to be called
something like site-tools <0.2 wink>.

  GvR> The introduction of the extra directory level "Tools" implies
  GvR> that idle is not importable as a package from regular Python.
  GvR> This is how I want it -- otherwise I could/would have made IDLE
  GvR> a package in the Lib/lib-tk directory instead of a directory in
  GvR> Tools.

I think the extra Tools directory still implies this, even if it isn't
in site-packages.

  GvR> I'd gladly accept a contribution of a setup.py file that does

  GvR> decided that I'd have to read it cover-to-cover to figure out
  GvR> whether what I want is even possible...)

Is there a reason why IDLE has this peculiar installation process?
Might there be a better way to do it now that we have distutils.  If
there is, we could put it in PEP 42.
