# Shell library for working with "chunk" files (commit-graph, midx, etc).
# corrupt_chunk_file <fn> <chunk> <offset> <bytes>
#
# Corrupt a chunk-based file (like a commit-graph) by overwriting the bytes
# found in the chunk specified by the 4-byte <chunk> identifier. If <offset> is
# "clear", replace the chunk entirely. Otherwise, overwrite data <offset> bytes
# into the chunk.
#
# The <bytes> are interpreted as pairs of hex digits (so "000000FE" would be
# big-endian 254).
