printf "\nunflat - Hierarchical Arrangement Script for the danbooru data folder 
Version 1 
Author: Glassed Silver 

This is a shell script and the methodical alternative to the fix script 77, 
only that this script doesn't intend to create any symlinks, 
but rather move all files in the root data folder and its sub-
directories crop, sample and preview to the non-flat, hierarchical 
file structure, that is now the only way danbooru stores files 
going forward. 

  IMPORTANT: MAKE SURE YOU BACKED UP YOUR 
  /home/danbooru/danbooru/public/data folder 
  and that you run this script as the danbooru user! 
  I take no responsibility for anything that gets borked 
  or breaks from this, so be cautious! Run this INSTEAD of 077_symlink_subdirectories.rb!\n\n\n"
