    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 compilation
      -post-compile:             called after compilation
      -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. 

    An example of overriding the target for project execution could look like this:

        <target name="run" depends="BlockInvaders-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.
