Ok this is going to be my official slackware post. I used to think it had weaknesses as a distro compared to others like gentoo with its aptget and the *BSDs with thier ports collection, but lately I've been finding a huge slackware community out there and great tools.

DOSSlack:

Slackupdate:
A script to check and update all the packages in your slack install. Even the kernel (although that might be a little scarry)
