Recently I tried to install a package in R version 1.8.1 for Windows. First I 
un".tar.gz"ed it and ".zip"ed it back in to be able to use the option Install 
package(s) from local zip files...

Unfortunately tis error message appeared:
Error in unpackPkg(pkgs[i], pkgnames[i], lib, installWithVers) : 
         Malformed bundle DESCRIPTION file, no Contains field


It's correct that the DESCRIPTION file does not have a Contains field, but I 
can't figure out why it's mandatory and what values it may contain. The manual 
Writing R Extensions doesn't even mention this field in paragraph 1.1.1

Any clues how I can make this package running? 
Note that it's not CRAN but self written, but as I'm told it have worked before 
(probably in a Linux environment).
