All I truly want a package manager for is to install an app in a location of my choice, make symlinks if I want them, and remove everything when I'm done with the app. Keeping track of all the user-modifiable files for each app and saving those when I "remove" would be nice too.
Yet there are 5-10 different package managers each with their own "ecosystem" of apps, and there are also a lot of apps I come across while browsing the web that say "here, download this .tgz!"; sure I'll click, but now I have a .tgz!
Does anything sort of like a "universal" package manager exist? Something with few features, just install and uninstall would be perfect as long as it will install/uninstall whatever I throw at it: .deb, .rpm, .tgz, .gem, etc.
All I want is install/uninstall through a single interface, a la App Store!
