Re: Python module for easy class generation

No problem then. I've modified my "classfactory" to keep the shared libraries in ~/.rootpy/dicts (now in my LD_LIBRARY_PATH). When I request a dictionary, it first checks for the library there (using a file containing a lookup table) and loads it, otherwise it compiles it there and adds it to the lookup table. No mess left behind, no bookkeeping required by the user, and no needless regeneration of the same dictionary by future requests.
