Except it's not its job. Python is a language not a configuration tool.

Well, the Eclipse core framework uses a plugin.xml which is very similar
to ZCML to glue its plugins.

The fact that RoR uses Ruby as a configuration language doesn't make it
more attractive for everybody, me included. More the opposite. The are
more attractive because of the buzz and their good community but that's
another topic.

I'm afraid, I'm sorry to disagree on this.

Does Java look weak for eclipse developers because it doesn't use java
properties for the configuration but XML files instead ? I don't think
so. Furthermore, Eclipse is implementing the OSGI specification
that is specifying only a manifest file for the plugins using java
properties but still they choose to do it with XML files -> because Java
is not a configuration tool neither !

I think Python guys, me included, are far too monomaniac regarding the
use of Python.

Though, I would agree with Philipp that we could make ZCML do less
regarding certain things.

I think ZCML is great and much easier, or should I say less difficult,
to teach to people, especially Java guys experienced with XML, who don't
know, or are not eager to learn, Python. (think integrators)
