A modern Python ruleset
summary
A pure Starlark Python ruleset (DBX build tools) that Bazel builds into self-contained runfiles with a hermetic Python interpreter, generated .pyc caches, and pip-driven wheel builds for third‑party packages including native C/C++ deps. It claims to handle millions of lines of Python in production, provides PyPI and local pip rules, PyTest integration, and a build file generator that infers deps from imports. Works well on Linux; Windows/Mac hermetic interpreters and cross‑platform distribution remain unfinished.
