# If you are copying this code to create
# another page, then read this
#
# You will surely need to change MyTreeDisplay.Prefix
# to reflect the root of the doc tree which your
# page is supposed to handle
#
# If you dont like the existing format of the page, or
# in any case want to change display different kind of
# info, then you will also need to change the
# defn of MyNodeControl. In particular all you will
# need to do is to change doccontrols.*
# and replace it or add more of the doccontrols.
# Look at utils/controls/doccontrols to see what
# choices you have. If what you want is not there
# consider making a new one and putting it there
# and just use it here.
