New submission from Nick Coghlan:

A thread on python-ideas made me realised the migration guide is currently 
missing a section: migrating integrated applications.

This needs to cover:

- "caniusepython3" to check dependencies for compatibility
- if dependencies are ready, and Python 2 compatibility can be dropped 
completely, the 2to3 based migration path
- if dependencies aren't ready yet, the Python 2 -> 2/3 source on Python 2 -> 
2/3 source on Python 3 -> Python 3 migration path
- if dependencies are ready but Python 2 compatibility is still needed, the 
Python 2 only -> 2/3 source on Python 2 or 3 -> Python 3 only migration path
