wtf is cut-in-the-guide?

CutInTheGuide is a script for Adobe Photoshop that automatically cuts an image apart using the guides already placed on the document. Guides in Photoshop are the lines a designer drags onto a canvas to mark where different sections should be, often used when laying out something like a set of icons, a sprite sheet, or separate panels within one larger image. This script appears to automate the process of slicing along those lines instead of doing it by hand. The README states it has been tested on Photoshop CC 2019 and newer, on both Windows and macOS. The script itself comes as a single file with either a .jsx or .jsxbin extension, both standard formats for Photoshop scripts. There are two ways to use it. The first is a permanent installation, where you copy the script file into Photoshop's Scripts folder inside the application's installation directory, then restart Photoshop so the script shows up permanently under the File menu's Scripts submenu. The second is a quick, one-time way to run it without installing anything, by opening the Scripts Browse dialog from the File menu and selecting the script file directly. The usage instructions in the README are quite brief and include some placeholder text rather than fully written out steps, so the exact workflow, such as what needs to be prepared before running the script or what happens once it finishes, is not spelled out in detail. Based on what is given, the general idea is to open a document with guides already in place, launch the script from the File menu, and follow whatever prompts appear until the cutting process completes. Given how sparse the documentation currently is, this looks like an early or minimally documented release rather than a polished, fully explained tool.
