+  with a slash to have the local file name used remote too, we now no longer
+  use the local directory as well. Only the file part of the -T file name
+  will be appended to the right of the slash in the URL.

+Daniel (7 December 2001)
+- Michal Bonino pointed out that Digital Unix doesn't have gmtime_r so the
+  link failed. Added a configure check and corrected source code.
