How can the Mustache renderer be configured to provide more informative output when templates are not found or rendering fails in PHP programs?

To provide more informative output when templates are not found or rendering fails in PHP programs using the Mustache renderer, you can set the Mustache's `strict_variables` option to true. This will cause Mustache to throw exceptions when it encounters missing or invalid variables in the template, providing more detailed error messages. 

<?php

require 'vendor/autoload.php';

use Mustache_Engine;

$mustache = new Mustache_Engine([
    'strict_variables' => true
]);

$template = 'Hello, {{name}}!';
$data = [];

try {
    echo $mustache->render($template, $data);
} catch (Mustache_Exception_UnknownTemplateException $e) {
    echo 'Template not found: ' . $e->getMessage();
} catch (Mustache_Exception_UnknownVariableException $e) {
    echo 'Variable not found: ' . $e->getMessage();
} catch (Mustache_Exception_SyntaxException $e) {
    echo 'Syntax error in template: ' . $e->getMessage();
}
