@defvr {Scheme Variable} waf-build-system
This variable is exported by @code{(guix build-system waf)}. It
implements a build procedure around the @code{waf} script. The common
phases---@code{configure}, @code{build}, and @code{install}---are
implemented by passing their names as arguments to the @code{waf}
script.
The @code{waf} script is executed by the Python interpreter. Which
Python package is used to run the script can be specified with the
@code{#:python} parameter.
@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,
