civicaml/bin

There are three binaries in the toolchain:

- The compiler "civcc", which compiles CiviC source code to assembly source

- The assembler "civas", which compiles assembly source to an object file that
can be run by the VM.

- The virtual machine "civvm", which runs one or more object files, one of
which should export a "main" function.

Additionally, there is a run script "run.sh" which takes one file name argument
and runs it through the entire pipeline, deleting intermediate files
afterwards. E.g. for the first assignment you may want to run:
$ bin/run.sh euclid.cvc
