//@ ### exec(command [, options] [, callback])
//@ Available options (all `false` by default):
//@
//@ + `async`: Asynchronous execution. Defaults to true if a callback is provided.
//@ + `silent`: Do not echo program output to console.
//@
//@ Examples:
//@
//@ ```javascript
//@ var version = exec('node --version', {silent:true}).output;
//@
//@ var child = exec('some_long_running_process', {async:true});
//@ child.stdout.on('data', function(data) {
//@ /* ... do something with data ... */
//@ });
//@
//@ exec('some_long_running_process', function(code, output) {
//@ console.log('Exit code:', code);
//@ console.log('Program output:', output);
//@ });
//@ ```
//@
//@ Executes the given `command` _synchronously_, unless otherwise specified.
//@ When in synchronous mode returns the object `{ code:..., output:... }`, containing the program's
//@ `output` (stdout + stderr) and its exit `code`. Otherwise returns the child process object, and
//@ the `callback` gets the arguments `(code, output)`.
//@
//@ **Note:** For long-lived processes, it's best to run `exec()` asynchronously as
//@ the current synchronous implementation uses a lot of CPU. This should be getting
//@ fixed soon.
