+  The namegrab() function, when given a list of dbrefs and a name, returns
+  the first dbref in the list that would match <name> as if you were
+  checking num() or locate(). An exact match has priority over non-exact matches.
+
+  namegraball() returns all dbrefs whose names would be matched by<name>.
