I've adjusted the commit message like so:

--8<---------------cut here---------------start------------->8---
    gnu: Add erlang-lfe.
    
    * gnu/packages/erlang.scm (erlang-lfe): New variable.
--8<---------------cut here---------------end--------------->8---

Made other small cosmetic changes such as moving the #:make-flags above
the #:phases, the inputs after the build arguments, added a copyright
line with your name, and installed it with commit 5ef28595e.

Thank you for your contribution!
