This Inkscape extension allows users to create a bounding box around selected objects or the entire page. The extension provides various options to customize the bounding box, including creating a new layer for bounding box, adjustments for size, addition of guides, and styling options for fill and stroke.

1. Download the Extension: Download the files bounding_box.inx and bounding_box.py from this repository.
2. Install the Extension: Copy these files into your Inkscape extensions directory. You will find this in the 'User Extensions' option under the System section at Edit-Preferences in Inkscape.
