Document Website has some issues

[zeng-github01]

• The craft function does not use the function style
• snippet.lua uses the wrong API

And add to this list the fact that the RC library has been completely emptied years ago but the wiki still has the old doc

I don't think any of us remaining here have any way of modifying ocdoc. @fnuecke ?
