Hey @ruyadorno! Thanks for this PR! Looks neat! I'm about to leave for 2 weeks so can't review this but I'll get back to you. Sorry!

[ruyadorno]

thanks for letting me know @arthurvr! meanwhile, any news on the new maintainers?

[ruyadorno]

@revathskumar I've seen you're catching up with the new APIs, feel free to help with the code review too :blush:

[arthurvr]

Thanks for the PR!

Can we also update the templates to use the new -%> trick? There are some files where that would be handy (_bower.json just to name one)

Me likey! No reason to start doing ping comments after 10 hours though. I don't have the bandwidth to review big PRs daily :p

[ruyadorno]

heheheh my bad, I just wasn't sure if you got the notification, didn't meant to pressure though, only arrived at work had the PR page still open and thought "oops, I should have pinged his username on the first message just to be sure"

[arthurvr]

@ruyadorno No worries :p
