  We build a dynamic query as a prelude, then @Template for each site
  with @Separator in between, and finally a postlude.
  First, the template, which may contain the following escape strings:
    ~n  the "pretty" site name (or close enough), e.g. 'Dba'
    ~u  the URL of the site, e.g. http://dba.stackexchange.com
    ~~  a literal '~'
