You are right, this is indeed the second iteration of the project. Since the first iteration (released about a year ago), many things have changed and been reworked. The most notable change is the introduction of the semantic-analysis framework. Lady Deirdre 1 was merely an incremental parser library.

It's just easier for me to organize the filesystem this way on my local machine. Everything that is unrelated to the development is outside of the work directory. Also, the license agreement refers to the "work". Perhaps it would be clearer for users if the work directory is clearly dedicated.

Everything that I planned to publish that is related to Lady Deirdre is already in the repository. I use this project for my other programming language project that I plan to release soon, but it will be in a separate GitHub repo. Actually, Lady Deirdre initially was separated from the language project codebase as I thought it may be useful for other programming language authors.
