can simply initialize it:
from an array. If you are inside Ruby and want to use a Bundler::Thor class, you
and invoke the command. This method is used when the arguments must be parsed
Parses the command and options from the given args, instantiate the class

  # This happens if a thor command is piped to something like `head`,
  # which closes the pipe when it's done reading. This will also
  # mean that if the pipe is closed, further unnecessary
  # computation will not occur.
