Zero Install is an open-source software installation system designed to allow users to install software on their computers without the need for a centralized installer. It is designed to allow for easy installation and updates of software, and is particularly useful for users with multiple operating systems or who need to install software on a limited number of computers. Zero Install also allows users to install multiple versions of software on the same machine or to install software from multiple sources. It is designed to work across multiple platforms, including Windows, Mac OS X, and Unix-like operating systems. Zero Install also allows users to install software from any source, including from third-party sites, and includes a feature for automated installation of software packages.
