How about some documentation on using this as a library?

[frankhaugen]

I get that this is a super-niche tool not unlike xsd.exe, so usability is not a huge priority, but the lack of clearity around how to use the generator nuget as a library, is frustrating.

I am looking into making a roslyn source generator that leverages this, but it seems pretty unclear how to use the code. Even looking at the tests is confusing me more, not less about how I could use this.

It would therefor be nice with a few lines of docs showing how to use this

This might help a bit: https://clang.llvm.org/docs/LibClang.html
