The mongomirror project is leveraging code from the mongo-tools project, but requires a few minor changes in order to work.

The changes are:

• exporting a few fields from the mongodump/mongorestore structs
• adding a new flag (not user-visible) that allows bypassing all user/role functionality in those tools

I've made a pull request here: https://github.com/mongodb/mongo-tools/pull/77.

Please let me know if there's anything I can do to help with this effort.
