* gnu/packages/file-system.scm (bees): New variable.
---

Submitting this patch for review and collaboration. Bees builds and
installs fine, and the runpath is correct. However, I have not tested
it against an actual filesystem.

I'm not sure if substituting all the external programs in the launcher
shell script should be factored out (I noticed several common regex
patterns when I was writing it), but I think it might be clearer as it is.
