    Process chapters downloaded by Tachiyomi into cbz files.


Optionally convert to cbz.


Requires termux.


cd into your Tachiyomi/downloads/SOURCE/TITLE folder before running--the script will identify source and title itself.


Note that termux does not have cwebp, it must be compiled/obtained elsewhere.


Also consider -near_lossless instead of -lossless.


THERE IS NO GUARANTEE THIS WILL WORK, OR THAT IT HAD NO TYPOS (I modified, working around a large number of symlinks and personal scripts I use, as well as changing the comments.


You are advised to back up your termux and Tachiyomi before runnin (/data/data/com.termux/files; /sdcard/Tachiyomi/downloads), and test on a single Tachiyomi chapter.


after running the script, manually check to make sure the chapters are in the correct order--the files are prefixed so they're opened in order by download/modification date, as not all titles are read in alphabetical order.

especially see insane tapastic comics that spell out their page numbers
worse yet, some that only include page number of current chapter, making it impossible to download at all grumble.

Yes, that's a thing
