In the letter from 09/12/2007 I had proposed you to install your 
optimizers to same path OpenOpt is installed, i.e. using from 
scikits.genericopt import ...
You had answered: "Do what you think is the best, I don't mind using 
from openopt... import optimizers"

I had got to know about those changes when Nils Wagner had informed me 
that latest OO from subversion just don't work.

Do you realize what any project will look like if anyone will implement 
his own changes wrt his own needs only, w/o even informing others?

I have committed some since v 0.17 (changes to ralg + bugfix to 
ALGENCAN), and I'm just waiting for GSoC decision that have to be 
announced 11 April. Since I had mentioned my intentions of participating 
in GSoC in my blog that had been connected to scipy-planet by someone, I 
guess you are aware of this. BTW anyone can have some holidays during year.

I still don't think some days of my not-committing give rights to those 
abstract people you have mentioned to do whatever they want with OO code.

And after those several months you can't wait these 2 days before GSoC 
results?
