+* Building the Command Line Incrementally
+
+  This is the recommended approach and caters also for pre-quoted command
+  line argument.
+
+** A simple example
+
+  Now we would like to build the following command line
+
+----------------------------------------
+runMemorySud.cmd 10 30 -XX:+UseParallelGC -XX:ParallelGCThreads=2
+----------------------------------------
+
+  using the following code snippet

+cmdl.addArgument("30");
+cmdl.addArgument("-XX:+UseParallelGC");

+dotnetfx.exe /q:a /c:"install.exe /l ""\Documents and Settings\myusername\Local Settings\Temp\netfx.log""

+File file = new File("/Documents and Settings/myusername/Local Settings/Temp/netfx.log");

+  When crafting a command line it would be really helpful to see what
