@mwop in this can it wasn't an adoptation but just a new build project. However when I read the code it's very likely that the authors had a look at my project. Class names are equal, and also the structure of the code looks much like the original project.
I would have been open to help them out, which I did before. If I just got a question. It's not that phpDocumentor is a new project. And with more that 7M downloads a month it's not that you can not trust it.
