// mass_email_script [--userid N] [--send] [--idfile X] [--batch N]
//
// send mass email.  Options:
// --userid     send only to the given user
// --send       actually send email
// --show_email show what would be sent rather than sending it
// --explain    show what we're doing
// --idfile     read user ID from the given file; otherwise send to everyone.
//              The IDs must be in increasing order
// --nocurrent  Don't send to current users
// --batch N    Do batches of N (default 1000)
//
// NOTE: a file "email_log" is used for checkpoint/restart.
// It stores a list of user IDs sent to.
// You must create this file (use touch) before starting
// (this is to prevent you from accidentally running this
// in the wrong directory and re-mailing a lot of people)
//
// see http://boinc.berkeley.edu/mass_email.php for info
