[Rd] License status of CRAN packages

Hi all,

I think for the common licences, we should also add BSD licence... for  
example my pkg randtoolbox (which is currently with incompatible  
licences) will probably be in a near future with the BSD licence.

Anyway I like the idea of two different repositories for GPL like  
licensed pkg and other packages.
