I don't dispute that. As a matter of fact, my team has been spending the 
last year-or-so cleaning up what had been growing "organically" for ten 
years. The code in the trunk (what will be MARY 4.0) should be 
substantially cleaner, better structured, and hopefully easier to 
understand and extend.

Yes, for some of the English language components. In MARY 3.6, also for 
the unit selection synthesis code.

Modularity has been one of the most basic design principles of MARY. You 
should be able to flexibly plug together the components you need. Each 
MaryModule has an input type and an output type; for any given request, 
the input data is passing through a (dynamically assembled) chain of 
MaryModules  to generate the output data. It means that you do not have 
to provide centrally the list of modules to apply -- this "emerges" from 
the available modules. I can see that this may look confusing, but it 
definitely is flexible.

Point taken, there are very many jar files. We should document 
dependencies as you would like to see them. This will take some time.

Yes, that is the purpose behind the config files in conf/ representing 
MARY components. They list cross-dependencies, and MARY has a 
"self-healing" mechanism (which works to some extent) which identifies 
missing components and offers to download and install them where that is 
possible.

Marc
