To build snudown with the C2Rust translator and/or cross-checks, initialize the git submodule by running git submodule update --init path/to/repo.

Make sure to build the derive-macros, runtime and rustc-plugin projects in the cross-checks folder beforehand. The runtime project must be built with the libc-hash feature (e.g. cargo build --features libc-hash).

Next, cd into the repo directory and run python setup.py build with one of the following arguments:

• --translate to translate the C code to Rust without any checks
• --clang-crosschecks to build the C version of snudown with full cross-checking
• --rust-crosschecks to translate to cross-checked Rust code
• --use-fakechecks may be appended to use the fakechecks library to print out the cross-checks, instead of libclevrbuf from the MVEE
• running with no flags will build the C version of the code
• Note that -f may need to be appended to the end of the command to force a rebuild, if building multiple times consecutively

After building any of the 3 versions, run python setup.py test to test it.
