This means that we write something like this:

    ;; Any of these licenses may be chosen.
    (license (list license:mpl1.1
                   license:gpl2+
                   license:lgpl2.1+))

I’d join these two lines.

Please don’t use the term “open source”; besides, all software in Guix
is free software anyway.  Just “FreeXL is a C library to extract …” is
sufficient.

Pushed with these changes to master with commit 623fb4d16.
