In this talk, we will discuss the classical definition of an orbifold and
the interpretation of this definition in terms of Lie groupoids.  In this
context, we will discuss groupoid actions on manifolds and Morita
equivalence.  For some basic examples of orbifolds, we will discuss torsors
for the associated groupoid.
