Consistent Hermetic Tooling with Actually Portable Executables
summary
Explains that Actually Portable Executables (APE) are single “fat” binaries containing x86_64 and aarch64 code that run on Windows, Linux, macOS and BSDs, and that the @ape Bazel module supplies wrappers/launchers to hermetically provide cp, mv, sed, awk, curl and Python without toolchain setup. Describes use of the Cosmopolitan C library and PKZip-packed data files inside the binary, the superconfigure build for common Unix tools, an ape_toolchain macro to register platform-specific tools, and exporting prebuilt Zstandard-compressed tarballs for repository rules.
