Tux Paint Stamps Installer XCode Project There are two steps to compiling the Tux Paint Stamps Installer application for Mac OS X. After opening the project: 1) Select "Stamps Archive" from the Active Target menu and click Build. This will generate the tuxpaint-stamps.tar.gz archive. 2) Select "Tux Paint Stamps" Installer from the Active Target menu and click Build. This will create the actual application (which bundles tuxpaint-stamps.tar.gz)
