You can either set YHC_BASE_PATH to something so that
"%YHC_BASE_PATH%/bin/yhc" will run Yhc, typically the location of the
inst folder if you are running from the source tree. Alternatively,
you can add your yhc executable to the Path, and Yhc will find the
other bits automatically.

I can't even find this on the wiki! Can you point me at the exact wiki
page, then I'll fix it.
