There currently isn't an official naming scheme for the PyPy executable for system installations. Of the 3 setups I've seen, the official build uses pypy, Arch Linux uses pypy, and Gentoo Linux uses pypy-c<version>. I brought up the similar issue of how to differentiate between Python 2 and 3 a while ago, but the conversation sputtered out.
One possible naming scheme includes these executables using Python 2.7, Python 3.3, and PyPy 1.9 as an example: pypy pypy-1.9 pypy2 pypy2-1.9 pypy3 pypy3-1.9 pypy2.7 pypy2.7-1.9 pypy3.3 pypy3.3-1.9 -Aaron DeVore _______________________________________________ pypy-dev mailing list pypy-dev@python.org http://mail.python.org/mailman/listinfo/pypy-dev
