+# Last update: 
+#   - fixed -L for years earlier than 2015
+#   - "/Users/${USER}" changed for "${HOME}" for better compliancy with home directory differents than /Users
+#   - Add wwdc 2015 video download (+ fixed issue with "Managing 3D Assets with Model I/O" session label).
+#   - fixed issue with names like I/O
+#   - adding download of ALL sample code (including those to grab on Apple documentation web site)
+#   - adding check for network connectivity (bash does not handle connectivity error for you)
+#   - fixing issue with name using comma in title (like ", part 1") - some might download them twice if using an early script - sorry ;(
