  A large class of supergravities in diverse dimensions are surveyed. This
includes maximal supergravities, their general gaugings in the framework of
embedding tensor formalism, supergravities with less than maximal
supersymmetry, their matter couplings and general gaugings. The emphasis is on
summarizing their most general form to date, and primarily in their component
formulation. A class of exceptional field theories in an extended geometric
framework are summarized briefly. For most of the supergravities surveyed, the
bosonic part of the Lagrangians and supertransformations up to leading terms in
fermions are given.
