// (0) This script corrects email addresses in the user database that are
//     not completely lowercase.  It also fixes cross_project_id values that
//     are zero.
// (1) these database error were probably introduced because of an omission
//     in create_account_action.php, that has been corrected in cvs.
// (2) accounts created in this way have cross_project_id set to zero.
//     This error is also fixed by the html/ops/make_emails_lowercase.php
//     script
// (3) script is safe to run multiple times and on databases with no errors
//     As supplied in cvs it is 'read only' and will only report problems
//     the user database.  It won't correct them, until it is edited by hand
//     to enable it to write changes to the database.
// (4) Just to be safe, back up your user database before running this script.
