[Fixed]-Use Django dumpdata to dump a subset of overall data?

A 3rd party django app, django-test-utils contains a makefixture command implementation which is basically a smarter dumpdata. You can specify exact model names with ID ranges to export (and it will follow related objects)
Example: manage.py makefixture --format=xml --indent=4 proj.appname.modelname[1:101] > test.xml
