+/** 
+ * A class to parse and extract information about shell commands. 
+ *
+ * ShellCommand can be used to:
+ *
+ * <ul>
+ *      <li>Take a command-line (eg "/bin/sh -c /path/to/my/script") and split it
+ *          into its component parts (eg. the command "/bin/sh" and the arguments
+ *          "-c","/path/to/my/script")
+ *      </li>
+ *      <li>Take a command and a list of arguments and combine them to 
+ *          form a complete command line.
+ *      </li>
+ *      <li>Determine whether the binary specified by a command exists in the
+ *          user's PATH.
+ *      </li>
+ *      <li>Determine whether a command-line specifies the execution of
+ *          another command as the root user using su/sudo etc.
+ *      </li>
+ * </ul>
