All of this is written in AsciiDoc. It's a simple mostly-plain-text markup language. You may want to look at:
To test your changes, first install
$ gem install ascii_binder
To build your changes, from the root directory:
$ asciibinder package $ firefox _package/main/index.html
Help wanted: We need Ruby packaging experts to help us get asciibinder into Fedora as an RPM.
