+# This script is used to generate the previews needed by the mod
+# It requires blender with the latest python API (2.6x is tested)
+# A script that works with older blenders and, maybe, without python, is available in older commits.
+# This script can also use pngcrush and imagemagick to reduce output size,
+#   please enable them if you want to push to the git repository of the mod.
+# Pngcrush output will be written to .previews/pngcrush_output
+# Warning: any file in .previews/ and u_skins/textures might be deleted without asking.
