PkgBase is a site that enables you to link to a package just by its name. When clicked, PkgBase will detect the operating system of the user and attempt to automatically install it. If this is not possible, directions are provided to install the package manually along with relevant links.

To construct a PkgBase link, simply append the name of the package to the end of pkgb.net:

http://pkgb.net/firefox

The link, when followed, will provide the appropriate action and/or instructions. Feel free to link to PkgBase from any site you want.
