(Slack) Attitude - Package management tool for Slackers

Slackers,

I am working on Package Management tool for my own Slackware based distro.
My aim is to develop usable tool for all Slackers.

Project Aim : Automate the package management using Shell Scripting
Planed feature list:

1. Automate the package management using Shell Scripting.
2. Handle multiple repository (Package Source) as per assigned priority.
3. Handle binary as well as source packages.
4. Work with Multilib setup.
5. Handle repositories having Official Slackware similar repository structure.
6. Handle repositories having SlackBuilds.Org similar repository structure.
7. Optional dependency handling.
8. Existing package backup.
9. Handle file conflicts between packages.
10. Verify installed packages.
11. Auto trigger running.
12. Separate tool for CLI and Ncurses mode.

Please suggest the any feature you need while working on Slackware.

Need discussion (planning) before implementation.
