Where is build.xml?

My headache pushed me to bed and had a sleep. I was thinking where is this build.xml file. Oh! God how will I find it? Do I need to search outside me? Outside me? What does that mean? It means I am WEB-INF folder. I was wearing a yellow dress. Why yellow? I guess it is because in Windows most of the folders are yellow in color by default. I was turning my head around in clock wise direction. That was a manual search of the file build.xml. I saw every thin in WEB-INF only. What about folders outside me? I will have to jump to see over the wall.Somehow I saw 'build' folder but can't see any one inside it. I was very much worried. Before I could search more, Ambily woke me up.
