That's cool.

There are two errors in the manpage:

The following sentence seems to be missing " with clang":
To build world and kernel, use the following instructions

Is world_clang.diff still required and not integrated into the tree?

The following seems to be missing a comma before "etc"
depending on which rules you follow:
The cpp, cc etc. programs

Shouldn't this "env CCVER=clang make" be "env CCVER=<version> make"?

Sounds good.

That makes sense.
