Also known as: ybegin, yEnc header
The header line that opens a block of yEnc-encoded data, carrying the original filename, the total file size, and the line length used. Multipart posts follow it with an =ypart line giving the byte range this article covers, and the block closes with =yend, which reports a CRC32 checksum. Newsreaders read these markers to reassemble segments in order and verify that nothing was corrupted.
