+//@
+//@ + `+/-e`: exit upon error (`config.fatal`)
+//@ + `+/-v`: verbose: show all commands (`config.verbose`)
+//@ + `+/-f`: disable filename expansion (globbing)
+//@
+//@ Examples:
+//@
+//@ ```javascript
+//@ set('-e'); // exit upon first error
+//@ set('+e'); // this undoes a "set('-e')"
+//@ ```

+//@ Sets global configuration variables
