[Buildbot-devel] Accessing other Build's properties from a BuildStep

[Daniel Rus Morales]

Hi Brian,

I've written a kind of tutorial on how to configure Buildbot to build projects 
with dependencies on each other. The case I draw builds a Django web app and a 
Django web project that depends on the app. It uses Triggerable schedulers and 
Trigger build steps.

Hope it resolves some of your doubts:
