SUMMARY = "Modern 3D graphics API with associated utility APIs"
DESCRIPTION = "Cogl is a small open source library for using 3D graphics \
hardware for rendering. The API departs from the flat state machine style of \
OpenGL and is designed to make it easy to write orthogonal components that \
can render without stepping on each others toes."
