"""Reassemble sharded folders produced by make_shards.py.
Finds every "<name>.zip-parts/" directory under the given root(s) and
unzips all shard zips inside it into the parent directory, reconstructing
the original "<name>/" folder. Safe to re-run (existing files are
overwritten with -o).
Usage:
python3 unpack_shards.py [root ...]
With no arguments, searches the current directory.
