Deig is a Java application which means it can be run on most platforms. It has been tested on OSX, Windows and Linux but only a very limited subset of possible versions and configurations.
The easiest alternative for Mac and Windows users is to download the installer. It includes a java runtime.
For other operating systems, or for those who want to optimize space, there is a zip-file that runs on computers with Java installed.
