# ARGV is where ruby stores command line arguments:
# http://ruby.about.com/od/rubyfeatures/a/argv.htm
#
command = ARGV.shift
# The first value in the ARGV array is the command the user typed (i.e. ./twitter timeline)
#
# Array#shift returns the first value from an array and removes it from the
# array: http://www.ruby-doc.org/core-2.1.2/Array.html#method-i-shift

arguments = ARGV
# After calling ARGV.shfit, ARGV contains the rest of the arguments we passed
# in via the command line. Unfortunately, on the command line, arguments are
# separated by spaces.  So, e.g.,
#
#   ./twitter tweet Hello everybody
#
# will result in the arguments array being ["Hello", "everybody"] after we
# use Array#shift to remove the first argument, i.e., "tweet".

results = run_app(command, arguments)

# It's up to you to present the results of each command.
