Clarify some of the documentation a little. Add in a few example scripts

2003-01-22  Glynn Foster  <glynn.foster@sun.com>

	* help/C/zenity.xml: Clarify some of the documentation a little. Add
	in a few example scripts and commandlines. I'm pretty useless at
	this though, since I don't know how to write scripts.

	* TODO: Update accordingly. Only 2 things left.
