Change the manpath, i. e. the directories where

<citerefentry><refentrytitle>man</refentrytitle><manvolnum>1</manvolnum></citerefentry>

looks for section-specific directories of man pages.

You only need to change this setting if you want extra man pages
|
|
(e. g. in non-english languages). All values must be strings that

are a valid path from the target prefix (without including it).

The first value given takes priority.
