%description
Alembic is an open computer graphics interchange framework. Alembic distills
complex, animated scenes into a non-procedural, application-independent set of
baked geometric results. This 'distillation' of scenes into baked geometry is
exactly analogous to the distillation of lighting and rendering scenes into
rendered image data.
