Hello Guix!

In the package-reference, there are fields called native-search-paths 
and search-paths. Unfortunately, the corresponding page 
(https://guix.gnu.org/manual/en/html_node/package-Reference.html) in the 
manual doesn't explain much. In my experience of packaging I could 
understand vaguely about them. I would like to know more. :-)

[1] What are they?
[2] What are the differences between them?
[3] When to use one or the other or both?

Thank you!

Regards,
RG.
