Re: multiple geomanager

Hello Andrei,

I found a solution which you wrote on the RootTalk board. http://root.cern.ch/phpBB3/viewtopic.php?t=8933

It would be helpful for users if this tips could be merged into the HTML documentation.

Regards,

Due to a historical reason of the original program written by another person, I need to define each telescope geometry with an instance of TGeoManager. But as you know, TGeoManager or its derived class must be singleton.
