#
#It contents:
#
# function main()
# {
#
# ...
#
# $page = new CustomPage();
# $page->slug = $_GET['slug'];
# $page->getBy(array('slug'));

#
# $this->content = $tpl->publish();
# $this->display();
# }
#
#---------------
#CONDITIONS:
#---------------
#
#**DB_PREFIX="" (Default)
#
# maybe: db, db_clan, ...
#
#**Exist a custompage

#PROOF OF CONCEPT (BLIND SQL INJECTION):

#EXAMPLE:

#Result: admin's username has 5 characters (maybe = admin? :P)
