README for CASS engine [Ver 0.02]

1. The software will be installed to "c:\cass" directory.

2. We will periodically scan the photo directory selected by the user.
   You can change your selection by running "c:\cass\bin\config_dir.exe".

3. Run "start_cass_servers.bat" to start the servers and launch the
    web interface.
    We have two servers running: one is the cass_server.exe which is
    the main indexing server. The other is the webserver.exe which
    serve the contents.
    (We can index roughly 2 photos per second on P4 3Ghz computer.
    And we will rescan the photo directory every day to index newly
    added photos. You can use the web interface immediately after the
    cass_server started, but it might only have partial content indexed.)

4. Run "stop_cass_servers.bat" to stop the servers.

5. Alternatively you can run these to start the server one by one.
  1) cass_server_RUNME_1st.bat
  2) cass_web_server_RUNME_2nd.bat
  3) cass_web_user_interface_link_RUNME_3rd.bat

6. If you have some problem with the program, the easiest fix is
   trying to rebuild the database: 
  1) Run "stop_cass_servers.bat"
  2) Delete "c:\cass\data" folder.
  3) Run "start_cass_servers.bat"

 (If possible, please send the error log to me: zhewang@cs.princeton.edu
  They are located at: c:\cass\log_cass.txt and log_web.txt.
   They should only contain debugging messages and names of the files
   of your photo directory, not the photos! :)
  
To uninstall:
1. Run "uninstall.exe" under "c:\cass" to uninstall the software and the index database it created
     (It will remove anything under "c:\cass\"!)

FAQ:
1. How to use a web proxy for the "goog_img" search feature.
 Modify the file "c:\cass\cass_web_server_RUNME_2nd.bat": Add 
 this line: 
     set http_proxy=http://your_web_proxy_address:port
 before the line: 
     .\webserver >> ..\log_web.txt 2>&1
 (where your_web_proxy_address should be the IP address or DNS name of
   your HTTP web proxy, port will be the port number of the web proxy.
  For example: set http_proxy=127.0.0.1:8118
               set http_proxy=proxy.princeton.edu:8080)
