You do not need to build AutoMan yourself, as it is available via Maven as a JAR. However, if you want to hack on AutoMan, or if you just like building stuff, the AutoMan source code includes an SBT build script. The build script builds the AutoMan JAR for you, including downloading all of AutoMan's dependencies. The build script can also build the sample applications that are located in the apps directory. These applications are the ones used in our papers.
