+@defvr {Scheme Variable} zig-build-system This variable is exported by

+This build system adds @code{zig} to the package inputs, as well as the
+packages of @code{gnu-build-system}.
+
+There's no @code{configure} phase because zig packages typically don't need to
+be configured. The @code{#:zig-build-flags} parameter is taken as a list of
+flags passed to the @code{zig} command during the build.  The
+@code{#:zig-test-flags} parameter is taken as a list of flags passed to the
+@code{zig test} command during the @code{check} phase. The default compiler
+package can be overriden using the @code{#:zig} argument.
+
+The @code{zig-release-type} parameter can be passed to define the type of
+release to make. Possible values are: @code{safe}, @code{fast}, @code{small}.
+It's default value is @code{#f}, which doesn't include the release flag in the
+@code{zig} command, resulting in a @code{debug} build.
