Exceptions happen from a user code wether it is intentional or not. This section describes
how `spring-shell` handles exceptions and gives instructions and best practices how to
work with it.

Many command line applications when applicable return an _exit code_ which running environment
can use to differentiate if command has been executed successfully or not. In a `spring-shell`
this mostly relates when a command is run on a non-interactive mode meaning one command
is always executed once with an instance of a `spring-shell`. Take a note that _exit code_
always relates to non-interactive shell.
