After making changes to the tool xml, you can refresh any tool using the admin menu 
Reload a tool's configuration
option.
This only works for tools loaded at startup and AFAIK there is currently no way to load a brand new tool after Galaxy has started other than via the toolshed installation option or a server restart.
If you edit a wrapper (eg perl or python) script that is called by a tool xml, it loads afresh for every subsequent job - no need to do anything to the server.

Dear all, 

I just want to follow up with this question(see email below). I am afraid that it is lost in the traffic. 

Thanks,

Hi,

I am trying to add a tool into Galaxy. So far everything is ok except that I need to restart the server to make the tool showing up in the tool panel. 

So my question is that how to refresh the tool panel without restarting the server? 

After I install a tool from toolshed, I can see the tool immediately from the tool panel. This is exactly the function I want to implement in python. I was reading the code but too complicated. Could you point me the right place(code)? 

Thanks a lot. 

Best,
Huayan
