Generates the FreeMarker Generator website, which also contains the documentation. This module is used internally. The output artifact shouldn't be deployed to the Maven Central. The output is merely to be uploaded to our website. The source code can be part of the Apache released though.
This module is deliberately not built automatically when you build the top-level module. To build successfully, first you must build the freemarker-generator-cli, so that we will have target/appassembler. Then run the examples in target/appassembler, as the documentation includes the output of some examples. Only after these run mvn package in freemarker-generator-website.
