@code{#:python} parameter.
@end defvar
@defvar zig-build-system
This variable is exported by @code{(guix build-system zig)}. It implements
the build procedures for the @uref{https://ziglang.org/, Zig}
build system (@command{zig build} command).
Selecting this build system adds @code{zig} to the package inputs, in
addition to the packages of @code{gnu-build-system}.
There is no @code{configure} phase because Zig packages typically do not
need to be configured. The @code{#:zig-build-flags} parameter is a list of
flags that are passed to the @code{zig} command during the build. The
@code{#:zig-test-flags} parameter is a list of flags that are passed to the
@code{zig test} command during the @code{check} phase. The default compiler
package can be overridden with the @code{#:zig} argument.
The optional @code{zig-release-type} parameter declares the type of release.
Possible values are: @code{safe}, @code{fast}, or @code{small}. The default
value is @code{#f}, which causes the release flag to be omitted from the
@code{zig} command. That results in a @code{debug} build.
@end defvar
@defvar scons-build-system
This variable is exported by @code{(guix build-system scons)}. It
implements the build procedure used by the SCons software construction
