C<$options>, if present, must be a hash reference. All remaining
parameters are slurped into C<%locals>.
-What is rendered and how C<$template> is interpreted is determined by
-the options I<type>, I<inline>, I<partial> and I<no_layout>.
+What is rendered and how C<$template> is interpreted is determined
+both by C<$template>'s reference type and by the supplied options. The
+actual rendering is handled by L<SL::Presenter/render>.
-If C<< $options->{inline} >> is trueish then C<$template> is a string
-containing the template code to interprete. Additionally the output
-will not be sent to the browser. Instead it is only returned to the
-caller.
+If C<$template> is a normal scalar (not a reference) then it is meant
+to be a template file name relative to the C<templates/webpages>
+directory. The file name to use is determined by the C<type> option.
-If C<< $options->{raw} >> is trueish, the function will treat the input as
-already parsed, and will not filter the input through Template. Unlike
-C<inline>, the input is taked as a reference.
+If C<$template> is a reference to a scalar then the referenced
+scalar's content is used as the content to process. The C<type> option
+is not considered in this case.
-If C<< $options->{inline} >> is falsish then C<$template> is
-interpreted as the name of a template file. It is prefixed with
-"templates/webpages/" and postfixed with a file extension based on
-C<< $options->{type} >>. C<< $options->{type} >> can be either C<html>
-or C<js> and defaults to C<html>. An exception will be thrown if that
-file does not exist.
+C<$template> can also be an instance of L<SL::Presenter::EscapedText>
+or a reference to such an instance. Both of these cases are handled
+the same way as if C<$template> were a reference to a scalar: its
+content is processed, and C<type> is not considered.
-If C<< $options->{partial} >> or C<< $options->{inline} >> is trueish
-then neither the HTTP response header nor the standard HTML header is
-generated.
+Other reference types, unknown options and unknown arguments to the
+C<type> option cause the function to L<croak>.
-Otherwise at least the HTTP response header will be generated based on
-the template type (C<< $options->{type} >>).
+The following options are available (defaults: C<type> = 'html',
+C<process> = 1, C<output> = 1, C<header> = 1, C<layout> = 1):
-If the template type is C<html> then the standard HTML header will be
-output via C<< $::form->header >> with C<< $::form->{title} >> set to
-C<$locals{title}> (the latter only if C<$locals{title}> is
-trueish). Setting C<< $options->{no_layout} >> to trueish will prevent
-this.
