We have big plans for using CommandBox to install packages from all sorts of code endpoints-- local folders, Git/SVN URLs, private corporate repos, etc. Version 1.0 of CommandBox focused on ForgeBox though, which is our CFML code depot. It may have started out as a ColdBox/ContentBox-specific thing, but is now open to the entire community to put any project they want on. I'm excited to already see entries like CFWheels, FW/1, MXUnit, and MonkehTweets on there. The more packages installable from CommandBox via ForgeBox, the more we all win.
Soon ForgeBox will get even more life of its own enhancing it with more functionality such as having multiple versions of the same package. We've already set up forgebox.io as the new domain for ForgeBox's HTML interface where you can search, sort, and filter the entries in your web browser. We've also built a "forgebox" namespace into CommandBox that uses the REST API to let you interact with ForgeBox from your console.
