What issue are you seeing?

I asked "Write documentation that explains how to use CoordinateSystem to someone who is already familiar with cairowindow at the level of tesseract.cpp." and then it adds a comment in front of the CoordinateSystem class that contains sentences like:

This is exactly what src/draw_coordinates.cxx does, once for the centered coordinate system and once for the painter coordinate system.
...
Internally CoordinateSystem allocates draw::Line and draw::Text
objects and stores them in std::vector<std::shared_ptr<...>> members.
Just like in src/tesseract.cpp, where you keep a std::vector of
shared_ptr<draw::Line> / shared_ptr<draw::Text> alive

a conversational chat, directly aimed at me "the user" in the context of my CLI chat session.
It seems that chatgpt doesn't know what "documentation" is :/.
