  * Prado build file.

- * This script compresses a list of Prado PHP script files

- * and merges them into one for performance redistribution.

+ * This is a command line script that can be run simply by "php build.php".

+ *

+ * This script expands prado.php into a file that contains the content

+ * of prado.php and all its included (directly or indirectly) files.

+ * Comments and trace statements are stripped off to further improve

+ * performance.

+ *

+ * The generated file is named pradolite.php and is placed under the

+ * 'framework' directory.
