  We determine that the deformation space of convex real projective structures,
that is, projectively flat torsion-free connections with the geodesic convexity
property on a compact 2-orbifold of negative Euler characteristic is
homeomorphic to a cell of certain dimension. The basic techniques are from
Thurston's lecture notes on hyperbolic 2-orbifolds, and the previous work of
Goldman on convex real projective structures on surfaces.
