+ * iptc_handle_t was available before libiptc was officially available as a
+ * shared library. Note, that when the shared lib was introduced, the API and
+ * ABI have changed slightly:
+ * 'iptc_handle_t' used to be 'struct iptc_handle *' and most functions used
+ * 'iptc_handle_t *' as an argument. Now, most functions use 'struct
+ * iptc_handle *' (thus removing one level of pointer indirection).
+ *
+ * HAVE_IPTC_HANDLE_T is used to determine which API ought to be used. While
+ * this is somewhat hacky, I didn't find better way to solve that :-/
