.SH NAME

roard \- RoarAudio sound server

.SH SYNOPSIS

\fBroard\fR [OPTIONS]...

.SH "DESCRIPTION"

\fBroard\fR is the most common RoarAudio sound server.
The RoarAudio sound server is the central component in a RoarAudio setup.
It mixes up diffrent audio streams from it's clients to send them
to it's outputs. Such outputs include soundcards, monitoring clients,
streaming servers and more.
