Adding an OPML-Export /feedlist.opml which is session-aware.
Unfortunately I couldnt create a class fitting to StringTemplate's needs, unfortunately Clojure seems not to be able to create Interfaces on-the-fly and one has to compile them before using them. I couldnt manage to do so, so I decided to create an OPML-String directly.
So far, this works. Anyway, added opml.st and opmlclass.clj - which somehow reflect my trial of doing this.
