just a heads up. It seems like the current master is really quite broken.
Detecting what has changed and re-generating seems to need fixing.
Which right now means often restarting awestruct - which is a pain
with thin. (see the Ctrl-C issue)
Unless someone has time to restore basic functionality we have to hold
back with a new release.
And we really should work on unit/integration tests so that such a big
regression does not sneak in again.
We're for some reason setting the relative_source_path to our generated output_path. Triggering the inner_release_page source_path from where it was loaded has no effect since no page with that source_path exists in site.pages
