DSL has built-in scripts to download and install Advanced Packaging Tool (APT). Once APT is enabled, the user can install packages from Debian's 'Woody' repository. Additionally, DSL hosts software ranging from large applications like OpenOffice.org and GCC, to smaller ones such as aMSN, by means of the "MyDSL" system, which allows convenient one-click download and installation of software. Files hosted on MyDSL are called "extensions". As of June 2008, the MyDSL servers were hosting over 900 applications, plugins, and other extensions.
