Oops. There was a typo there. That should of said.

Git isn't essential. I didn't know that llvm-lit was in pypi. It seems
that this version is quite out of date though. My lit.site.cfg files
work with upstream llvm-lit and when I try to use lit from pypi, I get

Hi,

Thanks for the reply.

I just noticed there was a typo in my last e-mail. That should of said
"I find the llvm-lit tool incredibly useful for other non-LLVM
projects. I'd like to setup a git mirror that only mirrors stuff in
utils/lit which I could then use as a git submodule".

Thanks. I didn't realise llvm-lit was in pypi, this is probably a
better solution. It doesn't seem this version has been updated in a
while though. I've been using upstream llvm-lit and when I try to use
lit from pip I get the following error message when it tries to load
my lit.site.cfg file.

```

@Daniel Dunbar: Any chance of updating the pypi lit package to
upstream llvm-lit?

Thanks,
