From what I remember, this code was completely rewritten, not just by 173210. The original repo was deleted so I'm not sure who to credit... sorry.

Because of the rewrite, I would call this a Version 2.0 - if this code really is the latest code from the original repo.

CTR_Toolkit - make_cdn_cia - Generates CIA files from CDN Content

Version: 1.1 by 3DSGuy and 173210

Usage

Usage: make_cdn_cia CDN_Content_Dir Output_CIA_File

CDN_Content_Dir - This is the directory where CDN content for the title for generating a CIA, is located. Do not modify any of the files, they must be raw.
