Again, it was hard to read and edit this text when it was in a string inside an echo command inside a bash script inside a heredoc inside a Ruby script wrapped in a mystery. It also gives me space to write some actual comments.
Having it all echo-ed into the file like that made it hard to read *and* hard to maintain. My initial aversion to it was that I didn’t want there to be an executable script in the main repository that only worked when you were in the VM, because people would just run it anyway. But this can be avoided by leaving it non-executable, and having a command in the VM that runs it instead.
