[Buildbot-devel] waterfall/jinja - where do variables like 'categories' come from?

[Stephen Davis]

Anyone?  It looks like it's not so simple since the per-build columns are seemingly in another variable.

Perhaps someone savvy with the internals could whip up a new waterfall.html template that grouped the builds by category?  Pretty please?

I am in the crowd of folks who misses the "order of builders = order they were added to config" waterfall display but I would be totally fine with it if I could use builder categories to group them together like the console page does.  I'm looking at the default templates, waterfall.html & console.html, and the former references a variable called "builders" to create the table columns and the latter uses "categories" and "slaves[c.name]" to create the columns.
