No files will be written when #dry_run is true.

file_output[RW]

When false the generate methods return a String instead of writing to a file. The default is true.

files[R]

Files to be displayed by this generator

json_index[R]

The JSON index generator for this Darkfish generator

methods[R]

Methods to be displayed by this generator

modsort[R]

        footer_file = @template_dir + '_footer.rhtml'

        <<-TEMPLATE
    <!DOCTYPE html>

    <html>
