I mentioned in my recent article about Git Subtree that I think the whole workflow is probably better managed with Composer. And that while I abstractly think that Composer is great idea for WordPress projects, I don’t particularly feel ready to use it in earnest.

It’s not uncommon for people, especially those new to a knowledge-area, to hear a word bandied about a lot and never really explained. I think “namespacing” is one of those words, and more importantly, it has two rather different meanings that you may need to know as a WordPress developer. So our goal is those two meanings, and then some of the implications of the more interesting version.
