title: How does the import files mechanisem work in Apache ANT
body: <p>I'm working on building a large scale project, as part of the build I defined a path in some xml and overridden it in another xml that imports it (or imports a file that imports it).
  I noticed that the order of the imports and the location of the overridden path tag in the importing files changes the behavior of the build.
  But, I couldn't find the logic behind it.
  How does the import work exactly?
  Thanks</p>
