//@ ### echo([options,] string [, string ...])
//@
//@ Available options:
//@
//@ + `-e`: interpret backslash escapes (default)
//@ + `-n`: remove trailing newline from output
//@
//@ Examples:
//@
//@ ```javascript
//@ echo('hello world');
//@ var str = echo('hello world');
//@ echo('-n', 'no newline at end');
//@ ```
//@
//@ Prints `string` to stdout, and returns string with additional utility methods
//@ like `.to()`.
