In order to build a manifest, i.e. to build all its modules, the manifest
needs to determine dependencies with other modules defined in the manifest
as well as dependencies with (third-party) libraries. A good example of how
such a mechanism would work is Maven. A single Maven-enabled project
contains a project.xml file in which binary dependencies are
defined. Maven reactor adds one extra methodology, where multiple modules
(projects in Maven terminology) are managed using a the
reactor tool.
Here's the Karma logic:
