66//! this tool.
77//!
88//! First, use the glibc, musl, FreeBSD, and NetBSD build systems to create installations of all the
9//! targets in the `glibc_targets`, `musl_targets`, `freebsd_targets`, and `netbsd_targets`
10//! variables. Next, run this tool to create a new directory which puts .h files into
9//! targets in the `glibc_targets`, `musl_targets`, `freebsd_targets`, `netbsd_targets`, and
10//! `openbsd_targets` variables. Next, run this tool to create a new directory which puts .h files into
1111//! <arch> subdirectories, with `generic` being files that apply to all architectures.
1212//! You'll then have to manually update Zig source repo with these new files.
