[XeTeX] arabic

[Jean-Louis Cordonnier]

I try to write a few word in arabic ;
I get this error message :
Package bidi Error: Oops! you have loaded package xunicode before bidi
packag
e. Please load package xunicode after bidi package, and then try to run
xelatex
on your document again.

I dont understand why (where in bidi documentation ?)
