 /**
  * This class is designed to put a file from the local filesystem to a WebDav Server
  * On the American Redhat Linux Server rented by ella-associates.org it is necessary 
  * to place the following paths on the java classpath
  *   /var/jakarta-slide-1.0.16/client/lib/webdav.jar:/var/jakarta-slide-1.0.16/client/lib/commons-httpclient.jar:
  *   /var/jakarta-slide-1.0.16/client/lib/webdavlib.jar:/var/www/utils/ 
  *
  *-------------------------------                 
  *<pre>
  *  Command line usage:                           
  *  java PutDavFile TheLocalFile TheWebDavLocationPath [user] [password] [server-url]  
  *    The purpose of this program is to put a file from the local file system onto a WebDav server 
  *    A WebDav Server is similar to an HTTP server but it allows the user to edit the files on the 
  *    server rather than just looking at them                      
  *  The program requires two parameters: 
  *    TheLocalFile  This is the file on the local file system which you wish to put on the WebDav Server 
  *    TheWebDavLocationPath  This is the location on the WebDav server where you want to put the file 
  *      which you are uploading. This should be a path using forward slashes (eg /some/directory/)   
  *  
  *  There are other option parameters  
  *    user       
  *    password   
  *    webdav-server-url    
  *  
  *  Examples:              
  *  ---------              
  *    java PutDavFile shopping-list.xml /documents/thingsToDo/     
  *
