++# Similarly, when using the nix package manager or the NixOS linux
++# distribution, man pages are stored in the packages' output store
++# path in /nix/store.  The globally installed man pages under
++# /run/current-system/sw/share/man are thus symlinks to files under
++# /nix/store.  By setting NIXSTOREDIR, mandoc won't ignore these
++# symlinks.
++# This setting can also be used to support Guix which is derived
++# from NixOS, but uses /gnu/store instead of /nix/store.
