Support imports in solcjs CLI

Given the following directory structure:

contracts/
  Source.sol
  Imported.sol

Where Source.sol:

pragma solidity ^0.4.0;

import './Imported.sol';

contract Source {
}

Running the following command:

solcjs --optimize --bin contracts/Source.sol

Based on the docs, I would expect the compiler to resolve the import but instead it throws:

contracts/Source.sol:3:1: Error: Source "contracts/Imported.sol" not found: File not supplied initially.
import './Imported.sol';
^---------------------^

If I include Imported.sol as a source file it will compile without error:

solcjs --optimize --bin contracts/Source.sol contracts/Imported.sol

Could you clarify my understanding here or is this a bug? Thanks! 🙃

so writing import is just a fun activity that solc dont understand ?

I solved this by doing the below as things have been improved as of 0.2.1:

var solc = require('solc');
var fs = require('fs');

var inputs = {
    'auction.sol': fs.readFileSync('auction.sol').toString(),
};

// Assumes imported files are in the same folder/local path
function findImports(path) {
    return {
        'contents': fs.readFileSync(path).toString()
    }
}

var compiledCode = solc.compile({sources: inputs}, 1, findImports)

fs.writeFile('compiled.json', JSON.stringify(compiledCode), function(err) {
    if (err) throw err;
    console.log('Compiled & saved');
});

I then read in compiled.json later in a .js file using web3 to use it via a browser using browserify:

compiledCode =  JSON.parse(fs.readFileSync('compiled.json').toString());

//console.log(compiledCode);

abi = JSON.parse(compiledCode.contracts['auction.sol:ContractName'].interface);
bytecode = compiledCode.contracts['auction.sol:ContractName'].bytecode;

Hope this is helpful to someone else.
