-m MODULE[:SYMBOL], -e MODULE[:SYMBOL], --entry-point=MODULE[:SYMBOL]
                        Set the entry point to module or module:symbol.  If
                        just specifying module, pex behaves like python -m,
                        e.g. python -m SimpleHTTPServer.  If specifying
                        module:symbol, pex imports that symbol and invokes it
                        as if it were main.
