[Carlos Pita <carlosjosepita@gmail.com>]

Sorry, this one is for emacs (the one in my previous email was copied
from the i3 report but it seems that something changed since then),
now it doesn't look very different to me:

  Root window id: 0xf5 (the root window) "i3"
  Parent window id: 0x1600164 (has no name)
     0 children.
