Plone's viewlets appear to be site-wide by default. How can I make a viewlet only appear on a certain page?

A:
This is done with Theme Interface in Plone. Check this documentation:
http://plone.org/documentation/manual/theme-reference/buildingblocks/components/themespecific
If u created your Theme / viewlet with a paster template, all should be in place and ready to use.
