 		- a backend is a shell script with a `listen` function
 		- this function is expected to continuously output post data it receives like so:
-```
-New post
-
-board:<board name>
-
-parent:<parent of post>
-
-user:<user>
-
-title:<title>
-
-content:<content>
-
-image_name:<name of image>

-image content:<base64 encoded image>

-End new post

 		- as long as the backend has a listen function that outputs data to stdout like this, 
 		shi doesn't care where it comes from.
