+    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-jar:                  called before JAR building
+      -post-jar:                 called after JAR building
+      -post-clean:               called after cleaning build products
+
+    (Targets beginning with '-' are not intended to be called on their own.)
+
+    Example of inserting an obfuscator after compilation could look like this:
+
+        <target name="-post-compile">
+            <obfuscate>
+                <fileset dir="${build.classes.dir}"/>
+            </obfuscate>
+        </target>
+
+    For list of available properties check the imported 
+    nbproject/build-impl.xml file. 
+
+
+    Another way to customize the build is by overriding existing main targets.
+    The targets of interest are: 
+
+      -init-macrodef-javac:     defines macro for javac compilation
+      -init-macrodef-junit:     defines macro for junit execution
+      -init-macrodef-debug:     defines macro for class debugging
+      -init-macrodef-java:      defines macro for class execution
+      -do-jar:                  JAR building
+      run:                      execution of project 
+      -javadoc-build:           Javadoc generation
+      test-report:              JUnit report generation
+
+    An example of overriding the target for project execution could look like this:
+
+        <target name="run" depends="pitiupi.screenCast-impl.jar">
+            <exec dir="bin" executable="launcher.exe">
+                <arg file="${dist.jar}"/>
+            </exec>
+        </target>
+
+    Notice that the overridden target depends on the jar target and not only on 
+    the compile target as the regular run target does. Again, for a list of available 
+    properties which you can use, check the target you are overriding in the
+    nbproject/build-impl.xml file.

+========================
+BUILD OUTPUT DESCRIPTION
+========================
+
+When you build an Java application project that has a main class, the IDE
+automatically copies all of the JAR
+files on the projects classpath to your projects dist/lib folder. The IDE
+also adds each of the JAR files to the Class-Path element in the application
+JAR files manifest file (MANIFEST.MF).
+
+To run the project from the command line, go to the dist folder and
+type the following:
+
+java -jar "pitiupi.screenCast.jar" 
+
+To distribute this project, zip up the dist folder (including the lib folder)
+and distribute the ZIP file.
+
+Notes:
+
+* If two JAR files on the project classpath have the same name, only the first
+JAR file is copied to the lib folder.
+* Only JAR files are copied to the lib folder.
+If the classpath contains other types of files or folders, these files (folders)
+are not copied.
+* If a library on the projects classpath also has a Class-Path element
+specified in the manifest,the content of the Class-Path element has to be on
+the projects runtime path.
+* To set a main class in a standard Java project, right-click the project node
+in the Projects window and choose Properties. Then click Run and enter the
+class name in the Main Class field. Alternatively, you can manually type the
+class name in the manifest Main-Class element.
