eGroupware 1.4.001.dfsg-2.1~bpo40+1 backported to etch

I did upload a updated version of eGroupware to my pool. You can grab it from http://ftp.cyconet.org/debian/archive/bpo/egroupware/1.4.001.dfsg-2.1~bpo40+1/ or via:

deb ftp://ftp.cyconet.org/debian etch-backports main non-free contrib

For installing the rules analog backports.org applies.

Have fun!
