<h3>Starting Single-File Compilation...</h3>
<?php
/* USAGE:
* php compile.php (or localhost)
* ? creates index_release.php in the same directory
*
* DEPLOYMENT:
* Copy index_release.php( + app.sqlite + icon.png) to your web server. Rename to "index.php".
* No src/ directory needed ? everything is in the single file.
*
* DEBUG BUILD:
* Set define('APP_DEBUG',true) in index.php ? compile produces index_debug.php instead.
* debug.js included, no minification.
*
* COMPRESSION (release only):
* PHP: php_strip_whitespace() per file, then newlines at top-level boundaries (function/class ends).
* CSS: comment + whitespace removal, split after } and ;
* JS: as-is (safe choice ? gzip handles the rest).
* Markers /* included from ? * / survive because compression runs BEFORE wrapping.
*/
