+// This file is essentially one level of a8straction a8ove urls.js (and the
+// urlSpec it gets its paths from). It's a 8unch of utility functions which
+// take certain types of wiki data o8jects (colloquially known as "things")
+// and return actual <a href> HTML link tags.
+//
+// The functions we're cre8ting here (all factory-style) take a "to" argument,
+// which is roughly a function which takes a urlSpec key and spits out a path
+// to 8e stuck in an href or src or suchever. There are also a few other
+// options availa8le in all the functions, making a common interface for
+// gener8ting just a8out any link on the site.
