create helper blocks


How can I create helper blocks for my extension. Like this one

Okay, I’ve figured out the trick now. The `options` file cannot be in the same folder as the main class; instead, it must be placed explicitly in the “helpers” subfolder so that it can be found. Like in this example:
|
|
|–helloworld.java
|–helpers
|----options.java

And JEWEL, thanks for the link. That really helped me out.
