# To Upgrade a component to a new version, change VERSION inside the function

# To Add a new component, add a new function, using one of the existing as
# a base start. Some of them download js/css files directly, some of them
# grab a zipped file or a tarball and uncompress it, copying over the needed
# data to the proper place, just try to find out what fits best for the new
# component and start from there.
#
# HINT: when installing a new component, comment the lines calling all the other
# components install functions, so you do not have to wait for all components to
# be installed.
