The procedure isn't available during package building
(well, (gnu build activation) _could_ be imported in a package definition
using #:imported-modules & #:modules but it is not supposed to be used like
that), so ‘Build Utilities’ doesn't seem appropriate, thus I'd suggest creating
an "Activation" section in the manual.

Maybe under ‘Programming Reference’, or after ‘Defining Services’ in
the ‘System configuration’ chapter?

Greetings,
