Modules/Visualization/Monteverdi/README.txt

-Monteverdi was developed 4 years ago in order to provide an integrated
-application for capacity building activities (teaching, simple image
-manipulation, etc.). Its success went far beyond this initial scope since it
-opened the OTB world to a wide range of users who needed a ready to use
-graphical tool more than a library of components to write their own processing
-chain. With this 4 years of lifetime, we have a lot of feedbacks regarding how
-useful the tool was, but also regarding what should be improved to move toward
-greater usability and operationnality. 
-We therefore decided to rework the Monteverdi concept into a brand new software,
-enlightened by this experience.
-
-Here are suggested steps for the Monteverdi beginner.
-
-1) Get the software.
-
-            http://orfeo-toolbox.org/otb/download.html
-
-2) The software is compiled using CMake http://www.cmake.org. CMake
-   generates Makefiles on Unix platforms, and Windows workspaces (or
-   appropriate) build files according to your compiler, operating
-   system, and other system variables.
-
-   Create a binary directory, and then run cmake. Provide to CMake
-   the source directory of Monteverdi and the binary directory that you
-   just created.
-
-   Monteverdi depends on OTB. You have to fill up the OTB_DIR variable with the
-   location of the compiled OTB. If you use ccmake or cmake-gui, you have an
-   interface to enter the value.

-You can get support :
-
-1. Using the OTB community site at http://orfeo-toolbox.org/
-2. Joining the otb-users mailing list at http://groups.google.com/group/otb-users
-
-Monteverdi source code is available at http://hg.orfeo-toolbox.org/Monteverdi
-
-There is many ways to join us in the OTB adventure and the more people
-contribute, the better the library is for everybody! See at
