[libcxx-dev] libcxx git svn incantations

Tue Jan 8 17:47:03 PST 2019

I’ve been using monorepo on Windows for close to 2 years and git-llvm
script works quite well. (Very) rarely there are issues with mixed line
endings, but it tends to happen on files that are intentionally CRLF. In
any case, I think you can definitely consider monorepo on Windows as
“supported” today
