USE VIM FOR BEST VISUAL FORMATTING

cd networks
make

* Step1: Run one or more servers as specifiedi below.

    cd server_$(server_name)_$(server_no)
    ./server_$(server_no)


                        $server_name    $server_no    Port 

    Iterative           iterative       1             9111
    Select              select          2             9222
    Multiprocessing     multiprocess    3             9333



* Step2: Run the client (or any of the datasets) using the format specified in question

    cd client
    
    Method 1:

        ./client hostname port myname add date(MMDDYY) start_time(HHMM) end_time(HHMM)  Message(only one word without spaces)
    
        example:
        ./client 127.0.0.1 9222 harsh add 092313 0800 0900 birthday
    
    Method 2:
        sh dataset_$(server_name) // This has specific set of add commands which would get run 


* Step3: Now we have added the data, now we can do any set of other operations like : get,getall,remove,update as format specified in the question statement

1. All Logical, Syntax and Semantic checks as specified in the question are implemented, they would come up as one starts checking for it.

2. Code is structured and behaves as following

    client: 

        1. Parse Args
        2. Checks for date, time, no._of_args etc.
        3. Send string in proper format to server

    server:

        0. Check for events that has already happened for all_users and remove them.
        1. Call appropriate function call (ex. event_add() for add)
        2. Get the args, make meaning from it.
        3. Perform appropriate actions on to the corresponding files.
        4. Send back response.

3. Multiprocessing (Not multi-threading) is used in the corresponding server using fork() system call. 

4. Files are used for storing the data, separate for every user.
    Ex.
        For user named 'harsh' -> filename: 'user_harsh' in server's folder

    There is also a 'userdir' ( User Directory File) which keeps track of user files.

5. Semaphores (Reader-Writer) are not implemented and thus its ramifications would follow.
