How to share code across multiple repository with Mercurial?

Over time, I developed a variety of utility functions, classes and controls that I reuse across multiple projects. For each of those projects I have a Mercurial repository and I copy the re-usable projects. Obviously this is bad since if I fix a bug in one of the reusable components, I have to copy the code manually in all repository and I could make a mistake in the process.

How do you handle such situation? How to share code across multiple repository with Mercurial in such way that if I do an update in one repository, I can easily integrate with the others.

Check out subrepositories: https://www.mercurial-scm.org/wiki/Subrepository

They won't help you keep the other copies up to date (you'll have to do that manually), but they will make that easy (you'd use hg pull; hg update in the subrepo, then commit the parent repo).

Another option (which I use on a different project) is to mandate a layout, then simply assume that the "utilities" repository is stored at ../utils, relative to each "real" repository.
