APT is one of those things that just makes linux super swell. There is one problem with APT though. This concerns the adding of repositories.

In Ubuntu, as an example, there is often the need to add a new repository if you want a major upgrade of a program, like from KDE 3.4.x to 3.5.x. And every time there is a long explanation of how you add a repository.

It is much harder than it has to be to add a repository. What I'm thinking of is a repository file that you can download and simply add by typing 
#> apt-get add [filename]
or simply doubleclick in X to add.

This file would contain the following posibilities:
o Adding one or more repositories
o Replacing one or more obsolete repositories
o Containing the key that the packages are signed with

There are probably lots of possibilities that I havent thought of, but this is definitly a start.
