I think the document needs a section on invoking Jam from the command-line.

You always need a Jamrules file in your project's root directory, if you
want to suppress this.

Yeah, sorry: features.jam needs to be in the top level directory. I am

Yeah, I guess so. Since it couldn't find features.jam, it didn't know that
<define> was a free feature. Some organizational work still needed here...
