-//@ ### exec(command [, options] [, callback])
-//@ Available options (all `false` by default):
-//@
-//@ + `async`: Asynchronous execution. If a callback is provided, it will be set to
-//@   `true`, regardless of the passed value.
-//@ + `silent`: Do not echo program output to console.
-//@ + and any option available to Node.js's
-//@   [child_process.exec()](https://nodejs.org/api/child_process.html#child_process_child_process_exec_command_options_callback)
-//@
-//@ Examples:
-//@
-//@ ```javascript
-//@ var version = exec('node --version', {silent:true}).stdout;
-//@
-//@ 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, stdout, stderr) {
-//@   console.log('Exit code:', code);
-//@   console.log('Program output:', stdout);
-//@   console.log('Program stderr:', stderr);
-//@ });
-//@ ```
-//@
-//@ Executes the given `command` _synchronously_, unless otherwise specified.  When in synchronous
-//@ mode, this returns a ShellString (compatible with ShellJS v0.6.x, which returns an object
-//@ of the form `{ code:..., stdout:... , stderr:... }`). Otherwise, this returns the child process
-//@ object, and the `callback` gets the arguments `(code, stdout, stderr)`.
-//@
-//@ Not seeing the behavior you want? `exec()` runs everything through `sh`
-//@ by default (or `cmd.exe` on Windows), which differs from `bash`. If you
-//@ need bash-specific behavior, try out the `{shell: 'path/to/bash'}` option.
-//@
-//@ **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.
