Hierarchy for developing several unrelated util packages

I developed a Java library and the package is called com.rachum.amir.util.permutation. I also have a github repo called Permutations, and an Eclipse project. Now I want to add some more stuff to my library, e.g., I want to develop a com.rachum.amir.util.range package. My question is how to ar开发者_运维知识库range the repositories/directory structure. Should I create a new Eclipse util project (or actually rename the current Permutation one), and create new projects within 'util`'s directories, or should I create a different, unrelated projects with just shared package names? Is it accustomed to create different git repositories for each sub-package or just one big one, or both?

Edit: Another conundrum is how to name the big package. util seems to be too general.

In general, you should have one repository for each element that will be released.

So, if your permutation package will be released independently from range, then have range be it's own repository. On the flip-side, if they will always be released together, then you should probably have a single util repository and have them both in there.
