# Commands can also be given with `!LAUNCH:`.
# This is especially useful when they contain `:`.

!LAUNCH: echo "I have a message for you:"

# Several commands can be tested at once.

echo -n "hello,"

$ The two commands ran successfully, but the third one, below, is not yet run
: message
: hello
0: world


# Running a command after a test resets the output buffer

echo "world"
0: message
0: hello
: world
