Since Pearhub is currently broken (unfortunately the project does not seem to
be actively mantained anymore) but we still want to have PEAR packages for our
library, we need to automate the creation of a package.xml definition file to
build the actual packages that will be uploaded on a self-hosted PEAR channel.
Onion, while still in its alpha stage right now, works perfectly fine for our
needs and its own package.ini file looks simple enough to edit and maintain.
See http://c9s.github.com/Onion for more details about Onion and thank @c9s
for making it available.
