Running Intruction :
    The source code consist of following directory structure
    <ROOT>---
            |--> src
            |--> inc
            |--> test
            |--> bin
             --> obj
             
    - All Source files are in src directory
    - All header files are in inc directory
    - All compiled object files are generated in obj directory
    - Exectuable "memcached" is  created in bin directory
    - Makefile is in <ROOT> directory    
    
To compile
$ make

To enable compilation logs use V=1
$ make V=1

To Permanently remove the logging statements from code
$ make TRACE_LEVEL=0
Trace level can be set to 0-4, from No logs to all debug logs
Once Removed these logs can't be enabled


To run the executable
$ ./bin/memcached      

following parameters can be passed
             
-h                      : Print help this message 
-V                      : Print Version
-v                      : verbose ( can be used multiple times), default = warn
                          -v    = ( error only )
                          -vv   = ( error and warning )
                          -vvv  = ( error, warning and information )
                          -vvvv = ( error, warnings, information and debug)
                          
                          
-u                      : Use UDP for Comunication (default : disabled)
-p port                 : port, default 5000
-k key_len              : Max Key Length in request or response message, default, 128
-l val_len              : Max Value Length in request or response message, default, 128
-t thread count         : Parallel Threads in Thread Pool, default, 1
-H Hash size            : Hash Size of hashtable, default, 256

Press Control + C ( SIGINT ) to stop the server

Testing 
A Test script rand_test.py is placed in test directory it can be used as follows
$ python test/rand_test.py <Number of Tests> <Port>
If no Port is given then 5000 is used as default port
If No arguments given then 100000 is used as test number
