  We advocate the study of supergravity models as well motivated few-parameter
low-energy supersymmetric models. In this context we survey a broad range of
phenomenological constraints and future tests, including present and
near-future Tevatron ($\tilde q,\tilde g,\chi^\pm_1,\tilde t_1$) and LEP
($h,\chi^\pm_1$) mass limits, collider indirect tests ($\Gamma_Z^{\rm
inv},R_b,m_t$), rare processes ($b\to s\gamma,(g-2)_\mu$), proton decay, and
dark matter (cosmology, direct and indirect detection).
