   1 # On macOS, system python binaries like /usr/bin/python and $(xcrun -f python3)
   2 # are shims. They do some light validation work and then spawn the "real" python
   3 # binary. Find the "real" python by asking dyld -- sys.executable reports the
   4 # wrong thing more often than not. This is also useful when we're running under
   5 # a Homebrew python3 binary, which also appears to be some kind of shim.
