+ *  rebuild.php - rebuilds all static files
+ *  This is much different than the one in vichan because we have way more static files. It will not work without pcntl_fork.
+ *  You must specify the things you want to rebuild. By default the script does nothing.
+ *  Example of how to use:
+ *	php rebuild.php --cache --js --indexes --processes 5
+ *  That will clear the cache, rebuild all JS files and all indexes, and fork 5 processes to do it faster.
+ *  I removed the quiet option, it's useless. Just use output redirection.
