torch-mlir/include/npcomp/runtime/README.md

This directory is named runtime instead of Runtime in order to be a slight reminder that it is a totally separate codebase from the compiler code. (There is no difference in naming conventions other than this one directory though)

It is best practice to keep compiler and runtime code totally firewalled. Right now, we don't have a good place to put the runtime code that fits in nicely with #include paths and stuff (we would like users to use something like npcomp/runtime/UserAPI.h to be the include path).

We could have a top-level runtime directory with runtime/include/npcomp/runtime/UserAPI.h but that just felt too heavyweight right now.
