@defvr {Scheme Variable} font-build-system
This variable is exported by @code{(guix build-system font)}. It
implements an installation procedure for font packages where upstream
provides pre-compiled TrueType, OpenType, etc. font files that merely
need to be copied into place. It copies font files to standard
locations in the output directory.
@end defvr
Lastly, for packages that do not need anything as sophisticated, a
``trivial'' build system is provided. It is trivial in the sense that
it provides basically no support: it does not pull any implicit inputs,
