-# Migrate ggml file(s) with ggmf magic to ggml file with ggjt magic
-#
-# We caused a breaking change to the file format on 2023-03-30 in:
-#     https://github.com/ggerganov/llama.cpp/pull/613
-#
-# (1) If you still have the Meta LLaMA .pth files, then close this
-#     file now; you can just run `convert-pth-to-ggml.py` again to
-#     migrate to the new format. The tool is easier to use too. It
-#     isn't necessary anymore to manage split output files because
-#     the new format always combines things into a single file.
-#
-# (2) If you deleted the Meta LLaMA .pth files due to save on disk
-#     space, then this tool is intended to help you.  Please check
-#     out the instructions below.
