repo-install
Repo-install is a common lisp package manager that can be used to chase down and download dependencies between common lisp packages. Unlike other package managers (asdf-install), repo-install maintains the connection between source code on your disk, and the upstream repository.

There are two primary advantages to this:

  1. Changes you make to your local copy of the package remain in place even when you update to a newer version of the package.
  2. It is much easier to submit patches to the upstream maintainer. For distributed version control systems, it is also much easier for the upstream maintainer to integrate your patches.
