Purpose
The purpose of these plugins to to make it easier to use a template epub (either epub2 or epub3) as the starting point while properly handling the unique id requirements of all epubs.

How it Works
Simply create a "template2" and/or "template3" folder(s) inside your Sigil Preferences Directory (for epub2 and epub3 respectively). To easily access that directory you can open Sigil's Preferences and use the "Open Preferences Location" button on the bottom left of the Preferences dialog.

Inside the newly created folder(s) unzip your template epub or use the FolderOut plugin to save an existing epub to this folder to become your template.

To load your template, launch the Template2 (for epub2) or Template3 (for epub3) plugin and it will properly update the unique id in your OPF and if needed in your NCX.

Limitations ...
Since unzipped files in open folders can be changed by other tools, any embedded fonts are stored unobfuscated and these plugins will refuse to work with folders that have an encryption.xml file present in the META-INF folder to prevent obfuscation/unobfuscation mismatches from destroying the font files. Before producing the final epub using Sigil (or any other software), the proper embedded font subsetting and/or obfuscating should be performed depending on the license of the fonts embedded.
