To test typed/untyped interaction:
$ racket main.rkt <BIN-DIR>
This compiles and runs a few small programs using the raco and racket
executables from <BIN-DIR>.
There is also a Makefile. Running make is similar to racket main.rkt $(which racket)
$ make
Each compile task and run task has a time limit. Anything slower than 10min gets killed.
See main.rkt for details.
