- Add a new postInstall hook that installs Chez's kernel.o file into the library directory. This library /should/ be installed by Chez, but isn't, and it's the only way to properly embed Chez in your applications or write your own shell/bootfile harness directly. - Fixes the version number for Nix to properly reflect the one Chez shows the user. - Loose odds and ends (fix homepage URL, tidy up comments) Signed-off-by: Austin Seipp <aseipp@pobox.com>
