Hi!
The build system arguments #:modules and #:imported-modules are not documented.
They are at least evaluated by the gnu-build-system, probably by even more build systems. I think the trivial-build-system only accepts a #:modules argument.
Further it seems important to also document %gnu-build-system-modules (and maybe others?) and its use inside #:important-modules.
The cookbook neither mentions one of these arguments.
Bye
