Agreed. And I like that distributing with LuaRocks forces me to take that into account. > (datafile supports 'contexts' which helps it finding files.

I was actually pretty surprised that LuaRocks doesn't promote `doc' up to a parent directory like `bin' is. It's a really nice feature of LuaRocks that after installing the Zile (and Specl!) rocks, the zmacs (and specl!) binaries are promoted into my PATH, without any extra fuss. Unix has a tradition of packages populating /usr/share/doc/<package> and /usr/share/man/man1/<package>.1, or similar, and thus users are used to being able to poke around in those directories to find documentation when they get stuck. Is there any way to set up my rockspec so that the manual pages and documents end up where users will expect to find them after installation (and preferably in such a way that `datafile' or similar will still be able to access them)?
