That's nice in many cases, but I was actually talking about subpackages in the meaning of that they won't be installed at the same time of QF4, only if the developer wants the extra stuff (hierselect or something) then they install it > Basically, when PEAR 1.4.0 comes out, you will be able to bundle the > preferred release of a subpackage directly, and specify it as normal > with a package.xml.
