That first sentence is a bit tautological, isn't it? I understand what 
you're trying to get at -- buildbot is a framework, not an application 
itself. But someone unfamiliar with the term may head off to Wikipedia, 
which seems to have a very different definition that you seem to from 
that definition:

https://en.wikipedia.org/wiki/Continuous_integration

In software engineering 
<https://en.wikipedia.org/wiki/Software_engineering>, *continuous 
integration* (*CI*) is the practice of merging all developer working 
copies to a shared mainline 
<https://en.wikipedia.org/wiki/Trunk_%28software%29> several times a day.

That, combined with your explanation of buildbot, would seem to say that 
buildbot does merges, which really isn't the case. It does its work 
after the merges are done.

Maybe a better way to say it might be:

"Buildbot is a framework that that aids developers in maintaining some 
of the best practices of Continuous Integration, such as automating 
builds, tests and deployments."
