AddApp allows you to install additional applications easily.

Note that AddApp is included in the ROX-All package. If unsure, start with that instead.

To install AddApp itself enter this command in a terminal window:

$ 0launch http://rox.sourceforge.net/2005/interfaces/AddApp

If you don't have the 0launch command, get it from the injector page. It's easy to install, as it's just a Python script (also included in ROX-All).

When the command is run, a dialog box should pop up confirming that you want to download and run AddApp:

Click on Run to download and run AddApp. You will now see a ROX-style savebox, offering to create a ROX wrapper for AddApp itself.

Drag the AddApp icon from the window into your Apps directory (or whereever you want it; this is just to create an easy way for you to run it).

Using AddApp to install other programs

The easiest way to install a new program is to drag its URL from a browser window onto AddApp's icon in a filer window. For example, drag the link http://rox.sourceforge.net/2005/interfaces/Edit to the icon now.
You will get another savebox, similar to the one above, but this time letting you create a wrapper for Edit.

More application URLs can be found in http://0install.net/injector-feeds.html.

Upgrading applications

The wrappers created by AddApp are not for specific versions of programs. Instead, they can be used to run any version. To change the version used, right-click on the wrapper in a filer window and choose Versions... from the menu.

This will display a dialog box letting you choose the version of Edit you want. Click on Refresh all now to check for newer versions. Double-click on the version number to change it if you don't want the latest one.
