+    There exist several targets which are by default empty and which can be 
+    used for execution of your tasks. These targets are usually executed 
+    before and after some main targets. They are: 
+
+      -pre-init:                 called before initialization of project properties 
+      -post-init:                called after initialization of project properties 
+      -pre-compile:              called before javac compilation 
+      -post-compile:             called after javac compilation 
+      -pre-compile-single:       called before javac compilation of single file
+      -post-compile-single:      called after javac compilation of single file
+      -pre-compile-test:         called before javac compilation of JUnit tests
+      -post-compile-test:        called after javac compilation of JUnit tests
+      -pre-compile-test-single:  called before javac compilation of single JUnit test
+      -post-compile-test-single: called after javac compilation of single JUunit test
+      -pre-dist:                 called before archive building 
+      -post-dist:                called after archive building 
+      -post-clean:               called after cleaning build products 
+      -pre-run-deploy:           called before deploying
+      -post-run-deploy:          called after deploying
+
+    Example of pluging an obfuscator after the compilation could look like 
+
+        <target name="-post-compile">
+            <obfuscate>
+                <fileset dir="${build.classes.dir}"/>
+            </obfuscate>
+        </target>
+
+    For list of available properties check the imported 
+    nbproject/build-impl.xml file. 
+
+
+    Other way how to customize the build is by overriding existing main targets.
+    The target of interest are: 
+
+      init-macrodef-javac:    defines macro for javac compilation
+      init-macrodef-junit:   defines macro for junit execution
+      init-macrodef-debug:    defines macro for class debugging
+      do-dist:                archive building
+      run:                    execution of project 
+      javadoc-build:          javadoc generation 
+
+    Example of overriding the target for project execution could look like 
+
+        <target name="run" depends="<PROJNAME>-impl.jar">
+            <exec dir="bin" executable="launcher.exe">
+                <arg file="${dist.jar}"/>
+            </exec>
+        </target>
+
+    Notice that overridden target depends on jar target and not only on 
+    compile target as regular run target does. Again, for list of available 
+    properties which you can use check the target you are overriding in 
+    nbproject/build-impl.xml file.
