Fair enough. Without seeing the code itself, one can only judge the book by its cover. I'm interested, but maybe not quite the target audience.
Unfortunately the code itself is in a style of C many find difficult to read. I blame my upbringing. ATW open sourced examples and it was not really helpful. More recently others are doing a step by step in more standard C https://github.com/ardentsia-cgs/kparser/
give it a spin! download is ~500kb for mac. It is however targeting folks who come from that world - but K/Q are absolutely worth exploring!
