/**
    * addusers.cpp
    * Written by Maxime Joanis
    * (phpBB support forum user MaxJ84)
    * 2008/10/21
    *
    * This program takes a list of user names (in a text file, one by row) and
    * returns a file with automatically generated passwords for each user and a
    * file addusers.php which can be placed in the root directory of a phpBB 3.x
    * forum installation to add the users all at once to that forum.
    *
    * You can use and modify this program according to your needs. Giving credits
    * for the original work is always appreciated!
