mzpp and mztext: Preprocessors
The "preprocessor" collection defines two Racket-based preprocessors for texts that can have embedded Racket code. The two processors share a few features, like several command-line flags and the fact that embedded Racket code is case-sensitive by default.
Note that these processors are not intended as preprocessors for Racket code, since you have macros to do that.
