    Executes the provided arguments inside the current vagrant VM,
    if present. Otherwise just executes the arguments. The entire
    command string MUST be quoted. All paths used must be relative
    to the root project folder shared between the host and VM.

Usage:
    bin/${0##*/} "Command [--with args]"

EOT

	exit ${1:-0}  # Exit with code 0 unless an arg is passed to the method.

# It is important that the last command is either the `vagrant ssh`
# or the `eval ...` so that the exit code of **this** script
# is the exit code from those calls.


# Logic matrix:
# vagrant installed + outside vm (no /vagrant mount point) = run in vagrant
# vagrant installed + inside vm = run native
# no vagrant + outside vm = run native
# no vagrant + inside vm = run native
