package.ps1 now fetches all dependencies
Don't literally check in Python since it looks dodgy (rightfully so). Instead the build script just fetches it. * Update README, simplifying language and documenting other projects

-"""Fixer for 'raise E, V'
-
-From Armin Ronacher's ``python-modernize``.
-
-raise -> raise
-raise E -> raise E
-raise E, 5 -> raise E(5)
-raise E, 5, T -> raise E(5).with_traceback(T)
-raise E, None, T -> raise E.with_traceback(T)
-
-raise (((E, E'), E''), E'''), 5 -> raise E(5)
-raise "foo", V, T -> warns about string exceptions
-
-raise E, (V1, V2) -> raise E(V1, V2)
-raise E, (V1, V2), T -> raise E(V1, V2).with_traceback(T)
-
-
-CAVEATS:
-1) "raise E, V, T" cannot be translated safely in general. If V
- is not a tuple or a (number, string, None) literal, then:
-
- raise E, V, T -> from future.utils import raise_
- raise_(E, V, T)
