  Given a simple, acyclic dimension group $G_{0}$ and countable, torsion-free,
abelian group $G_{1}$, we construct a minimal, amenable, \'{e}tale equivalence
relation $R$ on a Cantor set whose associated groupoid $C^{*}$-algebra,
$C^{*}(R)$, is tracially AF, and hence classifiable in the Elliott
classification scheme for simple, amenable, separable $C^{*}$-algebras, and
with $K_{*}(C^{*}(R)) \cong(G_{0}, G_{1})$.
