How do you set the view?

[spyderwebdesign]

What file requests the view from the url?

For example,
http://www.likdancewear.com/index.php?option=com_virtuemart&view=categories&virtuemart_category_id=0&Itemid=773

view=categories

What file requests that and uses it to set the view? I figured out if I change the value categoies to manufactures, then the manufactures will show on the page instead, but I can't find any code that uses $_GET['view']

Come one everyone. I can't be the first person trying make a custom link on my store to show a non standard vm view? I am trying to figure out what file looks at the url to set the view. Someone has to have done this already. I am just asking which file controls this.
