Compiling a smart contract without removing line breaks

I'm new to write a smart contract with Ethereum.

According to an official document, compiling a smart contract needs to remove all the line of a source code of the contract like:

    var greeterSource = 'contract mortal { address owner; function mortal() { owner = msg.sender; } function kill() { if (msg.sender == owner) suicide(owner); } } contract greeter is mortal { string greeting; function greeter(string _greeting) public { greeting = _greeting; } function greet() constant returns (string) { return greeting; } }'
    var greeterCompiled = web3.eth.compile.solidity(greeterSource)

https://ethereum.gitbooks.io/frontier-guide/content/contract_greeter.html

As I think the removing process is not *smart*, I want to compile the code itself like:

    var greeterCompiled = web3.eth.compile.solidity_infile( "greeter.txt" )
    # The function "solidity_infile" does not exists actually, 
    # but represents what I want to do.

**greeter.txt**

   contract
    mortal {
        /* Define variable owner of the type address*/
        address owner;
    
        /* this function is executed at initialization and sets the owner of the contract */
        function mortal() { owner = msg.sender; }
    
        /* Function to recover the funds on the contract */
        function kill() { if (msg.sender == owner) suicide(owner); }
    }
    
    contract greeter is mortal {
        /* define variable greeting of the type string */
        string greeting;
    
        /* this runs when the contract is executed */
        function greeter(string _greeting) public {
            greeting = _greeting;
        }
    
        /* main function */
        function greet() constant returns (string) {
            return greeting;
        }
    }

Does anyone how to do that?


The compiler I'm using is Solidity.
