This is yencode, an encoder/decoder package for the Usenet "yEnc" format, licensed under the GNU General Public License. * The encoder can output single part or multipart yencoded archives of any size. * Smart decoder can handle multiple files, including files specified out of order or with nonsense file names. * Easy to use Usenet posting software enables one-liner posting of individual files or groups of files, including creation of SFV/CRC checksum files if desired. * Optional scan mode: automatically locate and decode single or multipart yencoded archives in specified directories or recursively. * Fully compliant with all versions of the yEnc specification (currently v1, v2, v3). * Properly implements CRC values, including the pcrc32 on each part of multipart archives, and a crc32 for the last part of a multipart archive.
