+# Use this script in a bare Ubuntu distribution to install 
+# clang, libobjc2, GNUstep, and other dependencies that
+# will allow you to build and run Nu.
+#
+# libobjc2 is an updated runtime that seeks compatibility 
+# with Apple's modern Objective-C runtime. This new runtime
+# allows Nu to be ported to Linux+GNUstep without difficulty.
+#
+# Tested with ubuntu-14.04
+# Other Ubuntu and Debian installations may also work well.
+#
+# Thanks to Tobias Lensing for pointing the way.
