kvsetkeys
Key value parser with default handler support.
This package provides \kvsetkeys, a variant of package
keyval's \setkeys. It allows
the user to specify a handler that deals with unknown options.
Active commas and equal signs may be used (e.g. see
babel's shorthands) and only one level
of curly braces are removed from the values.
The package is part of the oberdiek bundle.
