//! To get started, run this tool with no args and read the help message.
//!
//! The build systems of musl-libc and glibc require specifying a single target
//! architecture. Meanwhile, Zig supports out-of-the-box cross compilation for
//! every target. So the process to create libc headers that Zig ships is to use
//! this tool.
//! First, use the musl/glibc build systems to create installations of all the
//! targets in the `glibc_targets`/`musl_targets` variables.
//! Next, run this tool to create a new directory which puts .h files into
//! <arch> subdirectories, with `generic` being files that apply to all architectures.
