Editors' notes

macutil is old, and essentially unmaintained. Use with caution, especially with the more obscure formats. One issue with some (all?) versions of it is that its CRC validation routine is incompatible with most 64-bit C compilers:

$ wget http://cd.textfiles.com/garbo/MAC/ARCERS/CPTEXPND.SEA
$ macunpack -v CPTEXPND.SEA
This is "MacBinary" input.
This is a "Compactor" self extracting archive.
Header CRC mismatch: got 0x9e5d4be6, need 0x13d15eac
