+Python to Rust transpiler
+This project started as Python to Rust syntax converter. It is not
+aimed at producing ready-to-compile code, but some basic stuff can be
+compiled easily.
+It generates unidiomatic non-optimized code with unnecessary
+allocations, but can reduce amount of edits you have to do when
+porting Python projects.
+Only basic subset of Python is supported right now and the end goal is
+to support common cases at least as a placeholders.
+The project is in experimental, so it may crash or silently skip some
+statements, so be careful.
+Based on Lukas Martinelli Py14
+(https://github.com/lukasmartinelli/py14) and Py14/python-3
+(https://github.com/ProgVal/py14/tree/python-3) branch by Valentin
+Lorentz."""
