This will be used by the jimeh/homebrew-emacs-builds brew tap repository
in combination with brew livecheck to automatically update cask formulas
to the latest nightly builds from the jimeh/emacs-builds repository.
The sign command signs Emacs.app application bundles with Apple's
codesign utility.
It does a few things outside of just executing codesign:
- Is aware of *.eln native-compilation files, which need to be
explicitly searched for on disk and passed to codesign, as they are
not detected when using the "--deep" option.
- Is aware of Contents/MacOS/bin/emacs CLI helper tool which we add into
the application bundle, and specifically passed it to codesign as
well.
- By default provides a set of entitlements which are relevant for Emacs
when running codesign.
