OptionalbboxPixel tolerance per coordinate for pairing bits by sourceBB (default: 8).
OptionalcontextContext lines kept around each change inside a hunk (default: 3).
OptionalinputInput format of BOTH documents (default: "auto", sniffed per side).
OptionallocateAdd source line numbers to bit references (bitmark inputs only; default: false).
OptionaloutputOutput format (default: "bitmark", the unified-style text). Ignored by diffBits.
OptionalsimilarityText-similarity threshold 0..=1 for pairing bits that share no id, box
or exact content (default: 0.6); 1 disables fuzzy pairing.
OptionalspacesSpaces around tag values in the rendered bitmark lines, 0..=10 (default: 0).
