Signatures Software comes with a digital signature, which is checked automatically by the system.

Uninstall Programs can be cleanly removed from the system easily (reversing the effects of the install). Multiple versions coexist Two versions of a program or library can be installed at the same time, and the user can choose which one to run.

See Sharing for how to set this up with Zero Install. Downloads shared between users If two users install/use the same program, it is only downloaded once and stored once. Upgrading a library will benefit all programs that use it. Libraries shared between programs If two programs use the same library, the library is only downloaded and stored once. User does not have to perform a full install operation manually on each package. Automatic upgrading The system can check for and install upgrades automatically or at the operator's request. Dependencies handled automatically If a program requires some library to function, the system will locate, download and install the library too.

Supports multiple platforms The same package format and command-line works across multiple operating systems, such as Linux and Windows. FeatureĮxplanation of features ¶ Non-admins can install software A normal user without administrator/root privileges can install software using this system (without unreasonable extra effort). Obviously, these things tend to be a bit biased (both in terms of what features are chosen for comparison, and of what is considered to be a 'pass') but it should give the general idea. This matrix shows some desirable features in a packaging system, and shows which systems provide them.
