- Development dependencies: debugging tools, test frameworks…
He then works through several of the issues involved with using each including having too many dependencies, untestable dependencies and conflicts. He then counters these with some helpful suggestions around them including the use of phars and using multiple repositories to break down the package and make it easier to manage their dependencies.
