[Chimera-users] installing chimera over an older chimera install?

[Tom Goddard]

Hi Sabuj,

  One more note about updating Chimera and plug-ins you  have installed 
separately.

  Sometimes updating Chimera requires updating plugin code too.  For 
instance, about half of the plugins on the Chimera experimental features 
web page had to be updated for Chimera version 1.2348 and later because 
they used the Numeric Python library and we replaced this with the NumPy 
library in 1.2348.  So the old plugin code would not work with the newer 
Chimera.  The versions of Chimera that a plugin works with are noted on 
the Experimental Features web page.

So maintaining plug-ins while updating Chimera is just a pain, and I am 
looking for a way to improve this situation.
