+Light Field Tools
+
+This script helps setting up rendering of lightfields. It
+also supports the projection of lightfields with textured
+spotlights.
+
+Usage:
+A simple interface can be accessed in the tool shelf panel 
+in 3D View ([T] Key).
+
+A base mesh has to be provided, which will normaly be a
+subdivided plane. The script will then create a camera rig
+and a light rig with adjustable properties. A sample camera
+and a spotlight will be created on each vertex of the
+basemesh object axis (maybe vertex normal in future 
+versions).
+
+    Vertex order:
+        The user has to provide the number of cameras or
+        lights in one row in an unevenly spaced grid, the
+        basemesh. Then the right vertex order can be
+        computed as shown here.
+         6-7-8
+         | | |
+       ^ 3-4-5
+       | | | |
+       y 0-1-2
+         x->
+
+There is also a tool to create a basemesh, which is an
+evenly spaced grid. The row length parameter is taken to 
+construct such a NxN grid. Someone would start out by adding
+a rectengular plane as the slice plane of the frustrum of
+the most middle camera of the light field rig. The spacing
+parameter then places the other cameras in a way, so they
+have an offset of n pixels from the other camera on this
+plane.
+
+
+Version history:
+v0.2.1 - Empty handler, multiple camera grid, r34843
+v0.2.0 - To be included in contrib, r34456
+v0.1.4 - To work with r34261
+v0.1.3 - Fixed base mesh creation for r29998
+v0.1.2 - Minor fixes, working with r29994
+v0.1.1 - Basemesh from focal plane.
+v0.1.0 - API updates, draft done.
+v0.0.4 - Texturing.
+v0.0.3 - Creates an array of non textured spotlights.
+v0.0.2 - Renders lightfields.
+v0.0.1 - Initial version.
+
+TODO:
+* Restore view after primary camera is changed.
+* Apply object matrix to normals.
+* Allign to normals, somehow,....
+* StringPropertie with PATH tag, for proper ui.
