For historical reasons we generated and hosted our own versions of the
API docs, mostly so we could keep multiple versions.
http://rubydoc.info is giving this to the community for free amd also
works with github to offer the latest docs, so we have decided to stop
generating and hosting our own API docs.
This changes the link on `fog.io` to reference `rubydoc.info` instead
and removes the uploading rake task.
It does not remove the `yard` rake task so documentation can still be
generated locally.
Fixes#1274
* Mentions changes should support 1.8.7 and 1.9
* Suggests looking at code metrics for possible help
* Updates config file for testing (now `tests/.fog`)
* Updated on fog.io docs as well
I think the docs could be opened up a lot more so this is a first pass
at improvements.
