It wouldn't work on OS X 10.10 until I added $APPNAME.app/Contents/Info.plist containing at least <plist><dict></dict></plist>

I created an app, but it won't execute when I double-click on the bundle. It is just a #!/bin/sh script that has a echo "hello world" statement in it for testing purposes. Can someone give me some guidance on how to get my app to run from clicking on the bundle? Appify did not create a Info.plist file for me, maybe this is the issue? What needs to be in that file? Thanks!

I forked this and added option-parsing, overridable icons file, and some other bits: https://gist.github.com/oubiwann/453744744da1141ccc542ff75b47e0cf
