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.
