This tag can be used to call getInfo from Module and NodeManager. The result of `getInfo' is a string which on default is written to the page. Most of this functionality doesn't have much to do with MMBase, and can be acquired with JSP or other taglibs too.
Consider using function tags in stead, which offer greater possibilities and flexibility.
