| Class | Description | 
|---|---|
| EnvUtilities | |
| ExecHelper | 
 This class is taken from Stephen Ostermiller's example at:
 http://ostermiller.org/utils/ExecHelper.java.html
 
 It provides some useful methods for manipulating and reading in the output of
 a  Processresultant from a call toRuntime.getRuntime()without using theProcess.waitFor()method, which apparently can hang
 on certain underlying systems. | 
| ExecUtils | Utilities for executing programs. |
