title: MongoDB import/export indexes
body: <p>I need a tool for rapidly recreating the proper "schema" (such as it is) of MongoDB instances between environments that pre-creates the right DB names, collections, sets collection caps, and creates the indexes for each collection.   I do NOT want to copy all of the data between the instances, though.  Each env I manage has different data but the DB/collection/caps/indexes are all the same.  Is there an easy way to do this, preferably a tool that exports a JSON doc of all the names, caps and indexes that can then be re-imported into a new instance?</p>
