-/**
- * Detects the language of a given piece of text.
- *
- * Attempts to detect the language of a sample of text by correlating ranked
- * 3-gram frequencies to a table of 3-gram frequencies of known languages.
- *
- * Implements a version of a technique originally proposed by Cavnar & Trenkle
- * (1994): "N-Gram-Based Text Categorization"
- *
- * Requires the language model database (lang.dat) that should have
- * accompanied this class definition in order to be instantiated.
- *
- * Example usage:
- *
- *
- * require_once 'Text/LanguageDetect.php';
- *
- * $l = new Text_LanguageDetect;
- *
- * $stdin = fopen('php://stdin', 'r');
- *
- * echo "Supported languages:\n";
- *
- * try {
- * $langs = $l->getLanguages();
- * } catch (Text_LanguageDetect_Exception $e) {
- * die($e->getMessage());
- * }
- *
- * sort($langs);
- * echo join(', ', $langs);
- *
- * while ($line = fgets($stdin)) {
- * print_r($l->detect($line, 4));
