There a lot of skin parameters, but only of a few there is some documentation with the different chart types.
It would be beneficial to have a list with the meaning (and charts where the parameter has an influence).
With the option -language one can get an overview of the skin parameters but no explanation and e.g. the skin parameter wrapWidth is missing in this list.
(question as a result of Is it possible to wrap swimlane headings automatically rather than using \n?)
