 `challengeutils` is a set of tools and commands that provides an interface for managing crowd-sourced challenges administered on [Synapse](https://www.synapse.org), including but not limited to, [DREAM Challenges](http://dreamchallenges.org/).  Its main purpose is to ease the process of creating, monitoring, and ending a challenge, as well as provide useful functions for post-competition analysis. _This package is being actively developed and maintained by DREAM and Informatics & Biocomputing (IBC), Computational Oncology Group at Sage Bionetworks._
