yEnc is a transfer encoding used for attaching files to Usenet newsgroup messages (and, rarely, e-mail and other kinds of messages). It is a more size-efficient alternative to Uuencoding.

It is justly characterized as "quick and dirty", requiring crude Uuencoding-style heuristics to detect it, instead of utilizing the robust-but-complex MIME standard that predates it.

Specifications

yEncode - A quick and dirty encoding for binaries v1.2 (.txt file)

Identification

A yEnc-encoded file is delimited by lines that begin with "=ybegin" and "=yend".
