This package provides a product build, release and installation system based on
package versions using zc.buildout. The core concept is taken from keas.build
and provides the same configuration syntax. The main difference is that we
don't setup the install script as ``install`` because there is a conflict with
the gnu install script call on ubuntu (pycairo, python waf install) used by a popen recipe (p01.recipe.setup:popen). This implementation will offer the
install script as a ``deploy`` entry_point.
