From 26c0da85cef1915c06661c913c4f2b5fb695a39f Mon Sep 17 00:00:00 2001

Subject: Replaced recursive call based directory listing with template
 application * using `apply-templates` with a call to `read-directory` as its
 `select` attribute is more straight forward * additionally it reduces code
 overhead and eliminates custom flow control ** i.e. its the superior way of
 traversing directories
