| .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 : |
