I'm trying to create a snapp from an app host on github (etherpad-lite).
When I launch the snapcraft stage command, snapcraft downloads all the files into the parts/etherpad-lite/src folder and then builds all that need to be built, and copies files into the stage/bin folder.
Now I need to copy some script from the source folder to the stage/bin folder.
How I can do that in snapcraft?
