We are going in circles here :)
"my hope is for a way of programmatically importing and updating new tools"
"This is currently possible (and very simple to do) using the Galaxy Admin UI"
I would call using the Admin UI not doing some programmatically.
You have done a brilliant job making easy to install and update tools
via the Admin UI. I am not sure the experience could be made any
easier. I have been instead trying to ask about how I might script
some of the actions you have enabled via the Admin UI.
My draconian theories about production environments aside, the second
use case - fully automating the creation of preconfigured Galaxy
instances for cloud images - that requires this functionality if I
want to use tool sheds, its not a taste thing. So I am going to
implement it - I need it, I just wanted your opinion on the best way
to go about it.
We should perhaps continue this conversation via pull request.
