+external/:  contains any third party library that needs to be used by ALTA.
+            Contains a modified QuadProg++ library using Eigen. You can
+            download and compile automaticaly some third party libraries using 
+            the Scons scripts.
+sources/:   contains all the source files. A Makefile or VS project can be 
+            created there from the .pro file. Scons generation of the
+            project is also supported.

-We use heavily the Qt profile functionality. To build some of the plugins you will
-be required to create your own system dependant .prf for any used library. For example
-all the rational BRDF fitters use the Eigen library. Therefore it is mandatory that you
-provide a eigen.prf file and that this file is in your QMAKEFEATURES directory.
