+//@
+//@ + `-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()`.
