How do I remove a module?
Use install module -u or the uninstall alias.
Removal
Installer removes only the selected extension block. It refuses to remove a core command, an active protected module or a hard dependency still required by another installed module.
Terminal removal
To remove the complete terminal use kill. To remove only .lil.php use kill -install; the bootstrap core remains able to reinstall Installer.
Examples
install help -uuninstall helpkill -install
