Code review comment for lp:~mvo/click/multiple-frameworks

We ought to avoid exposing the CLICK_FRAMEWORKS_DIR environment variable interface when it's only for tests; tests should be able to install mock functions as appropriate to override the frameworks directory. And as you say the default framework directory should be generated by configure - I suspect that undoing the change to click/paths.py.in from r372.1.1 would be enough for this.

However, this doesn't need to block merging, and you can clean it up at your leisure. Other than that I see nothing to complain about here. Thanks!
