+# Tests system-wide libavif shared library installation correct behavior, using Ubuntu in Docker. Run:
+#
+#     docker run -it ubuntu
+#
+# ... then run this script inside of there. When it finishes, avifenc and avifdec should
+# be in /usr/bin and offer all codecs chosen in the last cmake command in this script.
+#
+# An easy way to get this script into your running Docker container is to type (in the container):
+#
+#     cat > docker_ubuntu_shared_libs.sh
+#
+# Paste the contents of this script into the terminal, then hit Ctrl+D. You can then just run:
