CTAN Update: xargs
Two new features: 1. The usedefault key allows you, when using many consecutive optional arguments, to specify a value only for the last one if you want. 2. You can know make gobal (or even \protected) definitions easily with the addprefix key. Have fun!

xargs – Define commands with many optional arguments
The package provides extended versions of \newcommand and related LaTeX commands, which allow easy and robust definition of macros with many optional arguments, using a clear and simple xkeyval-style syntax.
