notes to who want to change code, developers:

although this library uses functions and global variables,
this library is called by two different install routines, install_1.php and install_2.php
so, even global variables are not passed to install_2.php normal way.
you should put any variables that you want to pass to install_2.php in passvariablestoinstall2 function..
