.SH "NAME"
Tirex::Renderer \- A Tirex renderer config
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
my \f(CW$r\fR = Tirex::Renderer\->new( ... );
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Tirex can work with several rendering backends such as Mapnik or \s-1WMS.\s0  A
backend can be started with different configurations, for the Mapnik backend
you need to configure the font directory for instance. This class defines
methods for reading the config files (/etc/tirex/renderer/*.conf) describing
the backend configurations and managing those renderers.
.PP
See the class Tirex::Backend and its subclasses for the actual code of
some backends.

Create new renderer config.
.PP
Every renderer has at least these general options: name, path, port, and
procs. Will croak if they are not all present.
.PP
In addition it can have zero or more options specific to this renderer.
.PP
Will croak if a renderer configuration already exists under the same name.
