Thanks!

'(package ...' should start on the second line, underneath the 'e' of
'define'.

There is a script 'etc/indent-code.el' in our Git repo that should
handle indentation for you.

The version string should be constructed as shown in the manual section
'Version Numbers':

https://www.gnu.org/software/guix/manual/html_node/Version-Numbers.html#Version-Numbers

This ensures that we can distinguish between different versions of
packages that are created from version control snapshots.

It's actually the Expat license:

Also, these fields typically go at the end of the package definition. It
makes no difference technically, but adhering to a common standard helps
reading and understanding the package.

We must leave a comment explaining why tests are disabled. If there are
no tests, then "No test suite." is enough.

I don't think we should use the shell, but instead use (assoc-ref) and
(string-append) to get the right path.

Instead, how about "No ./configure script.", since it communicates more
clearly why we delete this phase.
