+`gets()` and also added the `runme.sh` script to demonstrate it (using make was
+problematic). Cody notes that unfortunately this does not work with clang due to
+different compiler messages. Thank you Cody!

+work but it only works with gcc. Unfortunately due to the way the entry works

+this simply does not work with them. Can you help us?
