+# Build tmuxrdr from this checkout and install it as ~/.local/bin/tmuxrdr
+# (or $TMUXRDR_BIN). cargo's output is herdr's binary, target/release/herdr;
+# the name it is installed under is all the renaming there is -- it starts its
+# server from its own path, and src/config/io.rs gives it its own directories.
+#
+# Toolchains, found without PATH or shell-profile changes:
+#   Rust     the version rust-toolchain.toml pins, through rustup; Homebrew's
+#            keg-only rustup (/opt/homebrew/opt/rustup/bin) is used when no
+#            cargo is on PATH
+#   Zig      exactly 0.16.0, which herdr's vendored libghostty-vt requires:
+#            $ZIG, else ~/.local/opt/zig-0.16.0/zig
+#   sfw      Socket Firewall, which every crate fetch goes through (Zig's
+#            packages are fetched first, by Zig, hash-checked)
+#
+# The binary is replaced by a rename, so a running tmuxrdr server keeps the
+# old one until it is restarted.
