alertlevels

Purpose	By default TaskJuggler supports the pre-defined alert levels: green, yellow and red. This attribute can be used to replace them with your own set of alert levels. You can define any number of levels, but you need to define at least two and they must be specified in ascending order from the least severity to highest severity. Additionally, you need to provide a 15x15 pixel image file with the name flag-X.png for each level where X matches the ID of the alert level. These files need to be in the icons directory to be found by the browser when showing HTML reports.
Syntax	alertlevels <ID> <color name> <color> [, <ID> <color name> <color>...]
Arguments	ID	A unique ID for the alert level
	color name [STRING]	A unique name of the alert level color
	color [STRING]	The RGB color values of the color. The following formats are supported: #RGB and #RRGGBB. Where R, G, B are hexadecimal values. See Wikipedia for more details.
