UDECIDE helps you make decisions such as which software or hardware to 
purchase; ratings surveys; which project to pursue; selecting colleges, 
movies, stocks, or wines.  You enter a list of elements to evaluate the 
contenders, giving each a weight.  Then you enter the options, assigning 
values to each element.  Then sort to obtain an ordered list of the best 
options.  Or perform what-if analyses by changing elements or weights.
