Design
Rather than the normal method of downloading a software package, extracting it, and installing it before it can be used (with the accompanying use of destructive updates and privilege escalation), packages distributed using Zero Install need only be run. The first time software is accessed, it is downloaded from the Internet and cached; subsequently, software is accessed from the cache. Programs are accessed by the fully qualified name of their URL; for example one would not run "myeditor textfile.txt", but "http://www.example.org/edit textfile.txt". Inside the cache, each application unpacks to its own directory, as in Application Directory systems.
The system is implemented as a Python program, called the Injector (a reference to Dependency injection). The system is intended to be used alongside a distribution's native package manager.
Two advantages of Zero Install over more popular packaging systems are that it is cross-platform and no root password is needed to install software; packages can be installed in system locations writable by that user instead of requiring administrator access. Thus, package installation affects only the user installing it, which makes it possible for all users to be able to install and run new software.

Famous quotes containing the word design:
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (16131680)
“The reason American cars dont sell anymore is that they have forgotten how to design the American Dream. What does it matter if you buy a car today or six months from now, because cars are not beautiful. Thats why the American auto industry is in trouble: no design, no desire.”
—Karl Lagerfeld (b. 1938)
“For I choose that my remembrances of him should be pleasing, affecting, religious. I will love him as a glorified friend, after the free way of friendship, and not pay him a stiff sign of respect, as men do to those whom they fear. A passage read from his discourses, a moving provocation to works like his, any act or meeting which tends to awaken a pure thought, a flow of love, an original design of virtue, I call a worthy, a true commemoration.”
—Ralph Waldo Emerson (18031882)
