.SH SYNOPSIS
.IX Header "SYNOPSIS"
tirex-backend-manager [OPTIONS]
.SH OPTIONS
.IX Header "OPTIONS"
.IP \fB\-\-help\fR 4
.IX Item "--help"
Display help message.
.IP "\fB\-d\fR, \fB\-\-debug\fR" 4
.IX Item "-d, --debug"
Run in debug mode, and pass on the debug flag to workers
.IP "\fB\-f\fR, \fB\-\-foreground\fR" 4
.IX Item "-f, --foreground"
Run in foreground. E.g. when started from systemd service
.IP \fB\-\-config=DIR\fR 4
.IX Item "--config=DIR"
Use the DIR config directory instead of /etc/tirex.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
The backend manager starts and monitors as many backend workers as given in
the configuration. The backend processes do the actual rendering of tiles.
.PP
The backend manager expects each worker process to send an "alive" message in
regular intervals, and will kill the process if it does not do so in time.
.PP
The backend manager does not handle render requests in any way; these are read
directly from a local UDP socket by the individual backend processes.
.PP
If the backend manager receives a HUP signal, it will relay this signal
to all backends, causing them to exit after completing their current request.
It will reload the renderer and map configuration and re-start all workers
with the new configuration.
.SH FILES
.IX Header "FILES"
.IP \fI/etc/tirex/tirex.conf\fR 4

.SH DIAGNOSTICS
.IX Header "DIAGNOSTICS"
The backend manager logs to the \fIdaemon\fR syslog facility unless configured
otherwise. In debug mode, logging is also copied to stderr.
