Lathe Debugging for Racket is a small collection of utilities that are handy for debugging Racket code. This is a very ad hoc library, and the interface is subject to change.
This is a library for Racket. To install it, run raco pkg install --deps search-auto from the lathe-debugging-lib/ directory, and then put an import like (require lathe-debugging) in your Racket program.
The interface to Lathe Debugging is very tentative and unstable, but it is documented in the lathe-debugging-doc/ package's documentation.
