How do I import CIF files?

[jonesnc]

I have a CIF file that I want to import. When I go to System & Settings -> Migration Tool -> Import Content, click on Add Batch, and try to add a CIF XML file (in the Provide Mapping Presets field), I get this error:

This does not appear to be a valid concrete5 mapping file.

How do I specify that I want to import a CIF file, not a mapping file?

I should mention, I'm using the master branch, and the https://github.com/concrete5/addon_migration_tool/commit/59935b59c3df24c87f8b8c9d28d7befda87b062f commit.

It looks like the 5.7.5.x branch is working better.
