Okay, so now here is a tip on a tricky aspect of YAML syntax. How do
you create a multiline string in YAML that has backslashes and does
not end with a newline? Within a multiline string using either the
| or > character to indicate it, backslashes do not start escape
sequences, they are represented literally. Now, if you don’t want
there to be a trailing newline, you use |- as your indicator
character sequence.
