[Rd] contributed CRAN packages / Windows binaries for R-2.6.0

[Uwe Ligges]

To all CRAN package maintainers:

package maintainers might want to inspect the check summary provided on 
CRAN (CRAN/src/contrib/checkSummary.html) in order to clean up and fix 
packages that result in WARNINGs or ERRORs under some operating systems.

I will trigger to send out messages to those maintainers whose packages 
fail under today's R-2.6.0 beta for Windows. So don't be surprised.

Best wishes,
Uwe Ligges
