+### Advanced build
+
+The trace trees can be adjusted between tracing and building allowing for custom build layer creation.
+
+Some simple trace tree operators are provided for subtraction addition and intersection.
+
+Tree operations include `addTrees`, `subtractTrees`, `intersectTrees` and `extractTree`.
+
+#### Example - Exclusion
+
+In this example we build `app/core` excluding `app/corelibs`:
+
+```javascript
+  var builder = require('systemjs-builder');
+
+  builder.config({
+    baseURL: '...',
+    map: {
+
+    }, // etc. config
+  });
+
+  builder.trace('app/main')
+  .then(function(appTree) {
+
+    return builder.trace('app/corelibs')
+    .then(function(coreTree) {
+      return builder.subtractTrees(appTree, coreTree);
+    });
+  })
+  .then(function(appMinusCoreTree) {
+    return builder.buildTree(appMinusCoreTree, 'output-file.js');
+  });
+```
+
+#### Example - Common Libraries
+
+In this example we build `app/first` and `app/second` creating a separate `app/shared` library:
+
+```javascript
+  var builder = require('systemjs-builder');
+
+  builder.config({
+    // ...
+  });
+
+  var firstTree, secondTree, commonTree;
+
+  builder.trace('app/first')
+  .then(function(tree) {
+    firstTree = tree;
+    
+    return builder.trace('app/second');
+  })
+  .then(function(tree) {
+    secondTree = tree;
+    commonTree = builder.intersectTrees(firstTree, secondTree);
+
+    firstTree = builder.subtractTrees(firstTree, commonTree);
+    secondTree = builder.subtractTrees(secondTree, commonTree);
+
+    return builder.buildTree(firstTree, 'first-bundle.js');
+  })
+  .then(function() {
+    return builder.buildTree(secondTree, 'second-bundle.js');
+  })
+  .then(function() {
+    return builder.buildTree(commonTree, 'shared-bundle.js');
+  });
+```
