## プロジェクトの歴史と使われ方

crcany is Mark Adler's suite of programs for computing arbitrary CRCs and generating C code for efficient CRC calculation and combination.

### プロジェクトの歴史

The madler/crcany repository was created in 2016. Its README describes the project as a definitive reference for computing and combining any CRC with bit-at-a-time, byte-at-a-time, or word-at-a-time algorithms on big- or little-endian architectures.

### 採用の歴史

crcany is specialized infrastructure software rather than a broad end-user CLI. Its package appeal comes from bundling reference CRC definitions, code generation, test tooling, and small executables that can be built with make.

### 使われ方

The suite can compute CRCs from named catalogue parameters, combine CRCs from byte sequences, and generate .c and .h files for one or more CRC definitions. The README also documents a make test target that checks calculations and generated code against catalogued CRCs.

### パッケージ好きにとっての重要性

For maintainers and systems programmers, crcany matters because it turns CRC catalogue data into reproducible C implementations and tests. That makes it useful as both a command-line tool and a source-code generator for packages that need exact checksum behavior.

### タイムライン

- 2016: madler/crcany repository created.
- 2020: crcany 2.0 commit present in the official repository.
- 2021: crcany 2.1 commit present in the official repository.

### Related projects

- The README explicitly references Greg Cook's CRC catalogue and Ross Williams's CRC tutorial as the parameter and background sources that crcany consumes.
