) -> InstallMethod
Expand description

Work out how exe was installed.

Pure over its inputs - the resolved executable path, the home directory, the answer brew --prefix gave (if it was asked and answered), and the channel the user named - so every arm is testable without a Homebrew, a Scoop or a second machine.
