Comment (by mojca@…):

 I have a question for `pixilla`: what is the difference between
 `perl5.require_variant` and `perl5.set_default_variant`?

 I thought that `perl5.require_variant no` would create a bunch of variants
 without adding one by default, but it has no effect. It only has an effect
 if I set `perl5.set_default_variant` to no, but then I don't understand
 the difference between the two. Is this a bug?

 I'm attaching a patch for `xraylib`. It has a tiny flaw: one perl variant
 is enforced, but I would like to clarify what the functionality is
 supposed to be and then it should be trivial to fix that part. I would be
 grateful if the maintainer of `xraylib` could review the patch and
 possibly correct it in case of problems.
