Autopackage

Autopackage was a free computer package management system aimed at making it simple to create a package that can be installed on all Linux distributions, created by Mike Hearn around 2002.

In August 2010, Listaller and Autopackage announced that the projects will merge.

Projects such as aMSN and Inkscape offered an Autopackage installer, and Freshmeat.net offers content submitters a field to put the URL of Autopackages. The list of available packages is very limited, and most program versions are obsolete (for example, the most recent Autopackage of GIMP is 2.2.6, even though GIMP is now at version 2.8.2, as of August 2012).
