"Fossies" - the Fresh Open Source Software Archive

As a special service "Fossies" has tried to format the requested source page into HTML format using (guessed) Go source code syntax highlighting (style: standard) with prefixed line numbers and code folding option. Alternatively you can here view or download the uninterpreted source code file.

A hint: This file contains one or more very long lines, so maybe it is better readable using the pure text view mode that shows the contents as wrapped lines within the browser window.
