#
# The percentages of usage of servers are taken from the table and graph diagram
# reported in "Web Server Survey" page (found in Netcraft website)
# which are named: "Web servers developers: Market share of all sites".
# If the percentage of a web server developer goes below the standard threshold limit,
# then it is no more named in text below Netcraft graph diagram but its integer
# (without decimals) percentage of usage can be shown by pointing mouse cursor
# under the last point of one of the curves of the diagram graph.
# So the percentage of that historical web developer can be reported
# in its data table (see below) in order to continue to track it.
#
# NOTE: percentages about CERN server have been interpolated among 3..4
#       real values because not all quarters were available and
#       they have been rounded to integer part (no decimals)
#       along with "other" servers percentages.
#
