I very much agree with Michael. Maybe somebody actively working in  
image processing could look
  at the list of the modules and provide some feedback whether all  
should be included or a subset of most
important ones or maybe some modules could be merged?
The GIPE r. modules are definitely useful for environmental and land  
management applications
- the traditional field that GRASS was designed for.

My only concern is that the number of modules is large and may be  
difficult manage.
If the modules or their subset are included I propose to give Yann  
full SVN access
so that he can maintain the code.
