AppIndicator documentation for Python
Some links I've managed to find are...
- http://lazka.github.io/pgi-docs/api/AppIndicator3_0.1/classes/Indicator.html
- http://developer.ubuntu.com/api/devel/ubuntu-12.04/python/AppIndicator3-0.1.html
- http://developer.ubuntu.com/api/devel/ubuntu-13.10/c/AppIndicator3-0.1.html
- http://developer.ubuntu.com/api/devel/ubuntu-14.04
Since all these links are dead now, nowadays you can find the reference manual here:
