Miscellaneous
What about Python?
LCIO has a Python binding.
What about ROOT?
Marlin uses AIDA -> RAIDA -> Root (But there already exists RAIDA, which is "remote AIDA", so we appear to be running out of acronyms.)
What about FLUKA?
FLUKA is not open source, and it is not easy to interface to Geant4. The AliRoot framework has access to FLUKA.
What about Geant3?
Used by BRAHMS.
What about AliRoot?
4th concept is using it.
What about Gismo, LCDRoot, LCDG4, LCS?
These are all deprecated simulation packages. Parts of the last two were used in SLIC.
What about EGCS and GHEISHA?
These FORTRAN packages formed the basis for some Geant4 code, so they live on in spirit. EGCS is still quite useful, as it is still considered by many to be the most accurate EM physics package.
