+
+            Defining commands with many optional arguments made easy

+
+Presentation
+------------
+
+Defining commands with an optional argument is easy in LaTeXe. There is,
+however, two limitations: there can be at most one optional argument and it must
+be the first one. The xargs package provide extended variants of \newcommand &
+friends, for which these limitations no longer hold.
+
+You may know some tricks in order to define commands with many optional
+arguments, or with last argument optional, etc. Theses tricks are subject to a
+few problems (using arguments in arbitrary order can be difficult, sometimes
+space is gobbled where it should not), which can be difficult to solve.  Anyway,
+you don't want to worry about such tricky things while writing a document.
+
+The xargs package provides you with an easy and (hopefully) robust way to define
+such commands, using a nice key=value syntax.
