+    (description "@code{CoordinateTransformations} is a Julia package to manage
+simple or complex networks of coordinate system transformations.
+Transformations can be easily applied, inverted, composed, and differentiated
+(both with respect to the input coordinates and with respect to transformation
+parameters such as rotation angle).  Transformations are designed to be
+light-weight and efficient enough for, e.g., real-time graphical applications,
+while support for both explicit and automatic differentiation makes it easy to
+perform optimization and therefore ideal for computer vision applications such
+as SLAM (simultaneous localization and mapping).")
