"""Remote API version 2 baserlib.library.

PUT or POST?
|
| 25 |
============
|
| 26 |
|
| 27 |
According to RFC2616 the main difference between PUT and POST is that
|
| 28 |
POST can create new resources but PUT can only create the resource the
|
| 29 |
URI was pointing to on the PUT request.
|
| 30 |
|
| 31 |
To be in context of this module for instance creation POST on
|
| 32 |
/2/instances is legitim while PUT would be not, due to it does create a
|
| 33 |
new entity and not just replace /2/instances with it.
|
| 34 |
|
| 35 |
So when adding new methods, if they are operating on the URI entity itself,
|
| 36 |
PUT should be prefered over POST.
