from Products.PageTemplates.PageTemplateFile import PageTemplateFile

   index_html = PageTemplateFile('www/index_html', globals())
   manage_addForm = PageTemplateFile('manage_addForm', globals())

Not so bad, eh? ;-)  Some minor notes:  If you omit the file's extension 
  as above, the file must have extension '.zpt'.  If the base name of 
the file is different than the method name, you should add the keyword 
argument '__name__', as in:

   manage_addForm = PageTemplateFile('addForm', globals(),

Also, unlike DTMLFiles, PageTemplateFiles operate within the same 
restrictions as through-the-web PageTemplates (such as no access to 
names starting with underscores).
