That's about the size of it. I'm quite happy to work with a 3.4 alpha,
but when it comes to installation instructions, "get this and compile
it" is a lot less helpful than "install python3 via your OS package
manager" (especially since compiling Python from source also means
getting the development versions of whatever modules you need -
apt-getting a bunch of -dev packages, or whatever - and if you don't
get them, some modules mightn't work even though core Python does).
Hence I'd like to stick to OS-provided versions *where reasonable* -
I'm not going to warp my code around Python 2.4 unless there's a large
slab of users on that, but I will restrict myself to Pike 7.8.700
because it's worth the effort.
