@defvr {Scheme Variable} scons-build-system
This variable is exported by @code{(guix build-system scons)}. It
implements the build procedure used by the SCons software construction
tool. This build system runs @code{scons} to build the package,
@code{scons test} to run tests, and then @code{scons install} to install
the package.
Additional flags to be passed to @code{scons} can be specified with the
@code{#:scons-flags} parameter. The version of Python used to run SCons
can be specified by selecting the appropriate SCons package with the
@code{#:scons} parameter.
