Dear Guix,

I've added the Apache Software License 1.1 because I intend to submit a
package that uses this license later.  The GNU licenses page says the
following about it:

> This is a permissive non-copyleft free software license. It has a few
> requirements that render it incompatible with the GNU GPL, such as
> strong prohibitions on the use of Apache-related names.

Kind regards,
Roel
