All Implemented Interfaces:

Runnable
```
public class ChildMain
extends Thread
```
A wrapper class that invokes another class' main(String[]). This particular class uses several system properties to control features:
- Redirecting System.out and System.err.
- Displaying a minimized window in the Windows taskbar.
This class is normally not invoked directly. Instead, it is invoked by the LaunchTask class.
