(VBScript) Extract HTML Title, Description, Keywords

This example expands on the "getting started" example by showing how to access the HTML title, description, and keywords within each page spidered. These are the contents of the META tags for keywords, description, and title found in the HTML header.

'  The spider object crawls a single web site at a time.  As you'll see
'  in later examples, you can collect outbound links and use them to
