Keybase proof

I hereby claim:

  • I am zargony on github.
  • I am zargony (https://keybase.io/zargony) on keybase.
  • I have a public key ASDpUCG3MNWA4H9eSRQMGr_wi66LtkgLqa1eZya-GEXBggo

To claim this, I am signing this object:

# Do a map/reduce operation on the document's collection and return the results as one big
# hash. If a block is given, it is yielded with key and value for every result instead
# (this comes in handy if you expect large results)
