There is, +however, two limitations: only one argument can be optional and it must +be the first one. The xargs package provide extended variants of +\newcommand & friends, for which these limitations no longer hold. It +allows to control what happens with many consecutive optional arguments. +It also provide a way of making the definition global. + +Some features of xargs are similar to those provided by the experimental +`xparse' package, which also allows more flexible argument syntaxes, +though the approach and syntax are different. However, xargs is not +experimental, so I hope it can be useful while waiting for a stable +LaTeX3 release. + +Contents +-------- + +xargs.sty: the package itself +xargs.pdf: the (English) documentation and documented code +xargs-fr.pdf: the French documentation + +xargs.dtx: source for both documentations and package + +Version info +------------ + +2007-10-20 v1.0 First release +2008-03-08 v1.09 Added the usedefault and addprefix keys, not + documented yet... +2008-03-22 v1.1 Updated the documentation and fixed a bug in + \DeclareRobustCommandx, introduced in v1.09. + +License +------- + +This material is subject to the LaTeX Project Public License.
