.SH NAME
\fBzstd\fR - standard compression algorithm

.SH SYNOPSIS
.TP 5
\fBzstd\fR [\fBOPTIONS\fR] [-|INPUT-FILE] <OUTPUT-FILE>

.SH DESCRIPTION
.PP
\fBzstd\fR is a fast lossless compression algorithm
with highly parametrable compression strength and memory usage.
It is based on the \fBLZ77\fR family, coupled with FSE entropy stage.
zstd offers compression speed of 200 MB/s per core.
It also features a fast decoder, with speed > 500 MB/s per core.
\fBzstd\fR supports the following options :
