  Suppose $E$ is an end of an irreducible, properly convex, real-projective
$n$-manifold $M$. If $\pi_1E$ contains a subgroup of finite index isomorphic to
${\mathbb Z}^{n-1}$, and $E\hookrightarrow M$ is $\pi_1$-injective, then $E$ is
a generalized cusp. We list some consequences when all ends are of this type.
Under certain hypotheses we prove the holonomy of a properly convex manifold is
irreducible.
