[IronPython] Add reference to .dll located in above directory

[Dino Viehland]

Instead of sys.path.append('root') can you append the full path to sys.path?

That seems to work for me, I have:

Directory of F:\Product\1\Dlr\x

05/20/2010  10:34 AM    <DIR>          .
05/20/2010  10:34 AM    <DIR>          ..
05/20/2010  10:30 AM    <DIR>          module
05/20/2010  10:30 AM                64 PythonModules.cs
05/20/2010  10:34 AM             3,072 PythonModules.dll
               2 File(s)          3,136 bytes

 Directory of F:\Product\1\Dlr\x\module

05/20/2010  10:30 AM    <DIR>          .
05/20/2010  10:30 AM    <DIR>          ..
05/20/2010  10:36 AM                97 foo.py
               1 File(s)             97 bytes

Foo.py contains:

import clr
import sys
sys.path.append(r'F:\Product\1\Dlr\x')
clr.AddReference('PythonModules')

and both of these work:

10:37:08.72
F:\Product\1\Dlr > ipy x\module\foo.py

10:37:48.96
F:\Product\1\Dlr > cd x

10:37:50.11
F:\Product\1\Dlr\x > ipy module\foo.py

Also you could calculate the path using __file__ from foo.py.
