This package provides a Tcl-only implementation of the yEnc file encoding. This is a recently introduced method of encoding binary files for transmission through Usenet. This encoding packs binary data into a format that requires an 8-bit clean transmission layer but that escapes characters special to the NNTP posting protocols. See for details concerning the algorithm.
