     NAME
          qmail-newu - prepare address assignments for qmail-lspawn

     SYNOPSIS
          qmail-newu

     DESCRIPTION
          qmail-newu reads the assignments in QMAILHOME/users/assign
          and writes them into QMAILHOME/users/cdb in a binary format
          suited for quick access by qmail-lspawn.

          If there is a problem with users/assign, qmail-newu
          complains and leaves users/cdb alone.

          qmail-newu ensures that users/cdb is updated atomically, so
          qmail-lspawn never has to wait for qmail-newu to finish.
          However, qmail-newu makes no attempt to protect against two
          simultaneous updates of users/cdb.

          The binary users/cdb format is portable across machines.
