On Sun, 23 Mar 2008 Manuel Pegourie-Gonnard submitted an update to the
xargs
package.
The package provides extended versions of ewcommand and related LaTeX commands, which allow easy and robust definition of macros with many optional arguments, using a clear and simple xkeyval-style syntax.
Location on CTAN: /macros/latex/contrib/xargs Summary description: extented optional arguments handling License type: lppl
Announcement text: ---------------------------------------------------------------------- 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!
