-objects, basic data structures such as Image, Mesh, QuadEdgeMesh, and
-SpatialObjects, and common functionality for operations such as finite
-differences, image adaptors, or image transforms.")

-set(Filtering_documentation "This group of modules are filters that modify data
-in the ITK pipeline framework.  These filters take an input object, such as an
-Image, and modify it to create an output.  Filters can be chained together to
-create a processing pipeline.")

-set(Registration_documentation "This group of modules address the registration
-problem: find the spatial transformation between two images.  This is a high

-ITKTransform, \\ref ITKOptimizers, \\ref ITKFiniteDifference, and \\ref
-ITKFEM.")

-set(Numerics_documentation "This group of modules are basic numerical tools and
-algorithms that have general applications outside of imaging.")
-
-set(Video_documentation "This group of modules handles input, output and processing
-of static and real-time data with temporal components. It also handles communications
-to OpenCV and VXL external libraires.")

-set(Bridge_documentation "This group of modules are intended to bridge ITK to
-other toolkits as libraries such as visualization toolkits.")
