This parent site is automatically built on commit.

This is done by buildbot at:

https://ci2.apache.org/#/builders/91

The buildbot config file is at:

https://svn.apache.org/repos/infra/infrastructure/buildbot2/projects/commons-parent.py

The output is committed to the staging site at:

https://svn.apache.org/repos/infra/websites/staging/commons/trunk/content

Note that the staging site does not contain any of the components (proper/ dormant/ sandbox/)
These are published directly to the production site under (e.g.):

https://svn.apache.org/repos/infra/websites/production/commons/content/proper/

The parent site needs to be merged into the production site.
This is done using commons-site-publish.sh, now included in the buildbot script.
