-RustPython
-==============
-
-A Python interpreter written in Rust
-
-# Installation
-
-```
-bash init_env.sh
-```
-
-# Run
-
-```
-./test.sh <path/to/file.py> # compile and run
-./test.sh <path/to/file.py> --bytecode # print the bytecode in JSON
-./test.sh <path/to/file.py> --dis # Run python -m dis
-```
-
-## Manual
-Given a python file `test.py`
-
-```
-python compile_code.py test.py > test.bytecode
-
-cd RustPython
-cargo run ../test.bytecode 
-```
-
-# Testing & debugging
-
-```
-./test_all.sh # Run all tests under tests/
-```
-
-* If a test is expected to fail or raise exception, add `xfail_*` prefix to the filename.
-
-## Logging
-
-```
-RUST_LOG=debug ./tests_all.sh
-```
-
-# TODOs
-* Native types => Partial
-* Control flow => if(v)
-* assert => OK
-* Structural types (list, tuple, object)
-* Strings
-* Function calls => Blocked by bytecode serializer
-* Modules import
-* Generators
-
-
-# Goals
-* Support all builtin functions
-* Runs the [pybenchmark](https://pybenchmarks.org/) benchmark test
-* Run famous/popular python modules (which?)
-
-* Compatible with CPython 3.6
-
-# Rust version
-rustc 1.20.0-nightly
