That's it (conclusion for Raphaël: ask the mailing list instead of me ;) )

In fact Yade is a bit inconsistent, because this is ok:

$ yade-daily
Yade [1]: from mylib import *

Depending if the import is done in a script or typed within the session,
it will work or not.
This context switch is not really intuitive. One would expect that
typing in script or terminal is exactly the same.
It is not the first time I have trouble with that.

Could you guys try if any of the attached patches are working for you (I
only tested with IPython 0.10)?
The first one is trying to make the behavior the same for shell commands
and script by moving arguments handling after shell config.
The second is simply adding "sys.path.append('.')" in the startup
scripts, it is less general.
Naive tries, let me know if it works and what you think.
