Abstract
Almost-contact manifolds are considered as generalized almost-Hermitian manifolds of defect 1, which permits the use of the apparatus of the geometry of generalized almost-Hermitian manifolds to get a number of strong results, in particular to get a complete classification of important types of almost-contact manifolds. The theory of Q-algebras, which plays an important role in the apparatus mentioned, is presented in expanded form.
