How Are DFPs Distributed?

An initial set of DFPs is installed with the IDE.

After installation, DFPs are installed/managed automatically, using the Pack Manager in the IDE, which connects with the DFP repository on the web.

It's useful to know where the DFP source repositories are hosted, so you can archive the DFP file along with your IDE, compiler, and "packaged" project (.zip file) from MPLAB® X.
