=head1 NAME
testcolor.cgi - generate a table of colors to show which will be used for lines in graphs
=head1 DESCRIPTION
This is a CGI script that is designed to be run on a web server. It generates
an HTML page with the colors that will be used in graphs.
=head1 USAGE
B
In the text field, enter one or more names, separated by spaces. A grid of
colors will be generated with one row for each of the names. Each column
corresponds to a different color palette.
Color palette 9 is defined by a list of RGB colors in B

The B file controls the behavior of this script.
Create a custom color palette in the nagiosgraph configuration file by defining
a comma-delimited list of colors. Here are some sample palettes.
# rainbow: reddish, orange, yellow, green, light blue, dark blue, purple, grey
colors = D05050,D08050,D0D050,50D050,50D0D0,5050D0,D050D0,505050
# light/dark pairs: blue, green, purple, orange
colors = 90d080,30a030,90c0e0,304090,ffc0ff,a050a0,ffc060,c07020
# green from light to dark
colors = 80d080,50a050,308030

Copy B and B to a configuration directory
such as /etc/nagiosgraph.
Copy this file to a CGI script directory on a web server and ensure that
it is executable by the web server. Modify the B
