+# toradl
+
+Download and process icons from GameTora.
+Obtain permission from Gertas before using this program.
+
+toradl pulls the list of all skill icon IDs, character IDs, and rating IDs from the MDB
+Then, for each that has no previous output, it downloads the corresponding icon from GameTora.
+Each type is resized to various sizes and saved as PNG and AVIF.
