That's a good idea, although I was hoping there would be something in
R to do it for me.

I have ended up with:

	fwidth <- max(nchar(x[,1]))
	descs <- strwrap(x[,2], width=width - fwidth - 5, simplify=FALSE)
	
output <- do.call(rbind, mapply(function(name, desc) {
	cbind(c(name, rep("", length=length(desc)-1)), desc)
}, x[,1], descs))
	
	cat(paste(format(output[,1]), output[,2], collapse="\n"), "\n")

Thanks,

Hadley
