\fBsyd-hex\fR - Hex-encode/decode the given file or standard input
.PP
.SH SYNOPSIS
.PP
\fBsyd-hex\fR \fI[-hdeflsC]\fR \fI<file|->\fR
.PP
.SH DESCRIPTION
.PP
Given a file, hex-encode the file and print.\&
.PP
Given no positional arguments or "-" as argument, hex-encode standard input and print.\&
.PP
Use \fB-d\fR to hex-decode rather than encode.\&
.PP
Use \fB-s\fR with \fB-d\fR to hex-decode data with newline-delimited chunks.\&
.PP
Use \fB-C\fR with \fB-s\fR to warn and continue in case of read or encoding errors.\&
.PP
Use \fB-f\fR to force print decoded hex to TTY (insecure).\& By default,
decoded hex output is \fInot\fR written to standard output if it'\&s attached
to a TTY.\&
.PP
Use \fB-l\fR <human-size> to exit after size bytes are read.\&
.PP
Use \fB-l\fR <line-count> with \fB-s\fR to exit after count lines are read.\&
