ikiwiki has some pretty distinct fingerprints even when it's used
in unusual ways on sites that don't make it obvious it's being used:
* tova: a) rss and atom feed buttons
b) use of toc plugin on some pages
c) usual page.tmpl droppings
d) (I know the tova guys :)
* awesome: a) usual page.tmpl droppings
b) ikiwiki/ page and rest of basewiki pages exist
* UK software patents: used to use ikiwiki based on similar
fingerprints, but not now. Removed
