Hi Joost -- I think there may be 2 reasons why you can't find the package containing the guidelines: 1. "Guidelines" doesn't exist any more. It has evolved into the policy manual and the programmer manual, and 2. The P&P manuals aren't in a package (that I could find). They are uploaded seperately into doc/package-developer; the newest ones are in /private/project/Incoming. They are called policy.ps.gz, policy.html.gz, programmer.ps.gz, and programmer.html.gz.
HTH, Susan
