I recently tried writing my own ebuild and I used a for loop to install all contents of a directory, until someone pointed out, that I simply could use doins -r instead.
I can't find any mention about the recursive behaviour in the devmanual page: http://devmanual.gentoo.org/function-reference/install-functions/index.html
This could propably be added!
Patch ? :)
