django-smuggler makes use of the built-in Django management commands for dumping data. Loading data is done pretty much the same way as the loaddata command.

So basically just use Django's dumpdata/loaddata management commands. The dumps created by Django's dumpdata command are compatible with Smuggler's load action, and the other way around :).
