'Usage: dostart [OPTION]

Options:
    -b, --build: Build or rebuild services. Can be combined with --up to build while starting.
        > docker-compose build
        
    -u, --up: Create and start containers. Can be combined with --logs to view logs after starting.
        > docker-compose up -d
        > docker-compose up -d --build
        > docker-compose up -d && docker-compose logs -f -t
        
    -d, --down: Stop and remove containers, networks.
        > docker-compose down
        
    -l, --logs: View output from containers.
        > docker-compose logs -f -t
        
    -h, --help: Print this message.
        
Examples:
=>  To start the containers while also viewing the logs :
    $ ./dostart --up --logs
    
--> Equivalent to :
    $ ./dostart -u -l
    
    ------
    
=>  To build the containers without starting them :
    $ ./dostart --build
    
--> Equivalent to :
    $ ./dostart -b'
