I have updated my contrib code for version 6.5. In the attachment you will find the directories array, datetime, miscutil, string, tools and userlocks which replace the corresponding directories under contrib. In contrib/tools you will find some developement scripts which I use while hacking the sources. I hope they will be useful for some other people. I have also added a contrib/Makefile which tries to compile and install all the contribs. Unfortunately many of them don't have a Makefile or don't compile cleanly. -- Massimo Dal Zotto
