usage

split file into small files (no more than 1MB)

python3 -m cuffers <input_file> <output_folder>

<output_folder> will be automatically generated when you run this command, and all fractions will be saved in that folder along with a file named summary.<index>.json.

merge fractions into a whole file

python3 -m cuffers --merge <input_folder>

a merged file will be generated based on the fractions in <input_folder> and the name stated in <input_folder>/summary.<index>.json. the newly generated file will be placed right outside the folder <input_folder>, and if there has already been a file with the same name, the merge operation will be ignored (and you will get a warning output to stderr).
