This project has recently started. I don't recommend anyone use it just yet.

However, it is for anyone who wants

  • to get involved in development,
  • to give feedback,
  • or are happy with it's very limited state

Please check back often, I hope to get this to a generally useful state this year. Contributions, advice welcome, development is coodinated on github.

  • any authentication support
  • sync support (version 2.0)
  • paging, batch support
  • stable api
