Programming Assignment 10
1 Summary
    The (fictitious) company 
zmedia
    has been contacted by a number of libraries (at schools and
    colleges/universities and in towns/cities) that have requested
    a site licensing scheme of some kind.
    In response, they have decided to develop a 
    
bookz_server that can "deliver" 
bookz
    to any 
telnet client.
    
    Ultimately, the bookz_server will need to verify
    that the client request is coming from an IP address
    associated with a paying customer and use the appropriate
    collection of bookz. For now, however, those
    features are not required.
    
 
2 Specifications and Other Documents
  zmedia has provided you with the following documents.
    
 
3 Additional Specifications/Constraints
  In addition to conforming to the documents provided by zmedia (and
  all related course policies), your code must satisfy the
  following additional specifications/constraints.
  
- 
    To handle multiple requests concurrently, the 
bookz_server
    must be multi-threaded. Specifically, each connection must be
    handled in its own thread.
     
 
4 Testing Advice
- 
      Start testing using a single machine (and multiple terminal windows) but,
      ultimately, be sure to test your code using multiple different machines
      (i.e., with the server on one machine and the clients on other machines).
      
 
- 
      Start testing using a single client but, ultimately, test multiple
      simultaneous clients.
      
 
- 
      Make sure your tests include several simultaneous requests for the same
      
bookz (i.e., make sure your connection handlers don't
      step on each other if they are serving-up the same bookz).
       
 
5 Submission
  You must submit all of the files (including the makefile) 
  needed to build the bookz_server.
