py_singlefile_binary

This repository defines Bazel rules for building self-contained Python executables, including interpreter + standard library + application.

It's a proof-of-concept that we (@grailbio) are using for some developer tools. It's not extensively tested nor designed for reuse nor supported by us. It was extracted out of our internal repository so it includes a few patches and non-current dependency versions.

Usage:

$ bazel run //example
...
