adding nK users script?

[Roman Serbski]

Good day all!   I use Qmail 1.03 + Vpopmail 4.9.7 + Mysql authorization. I have almost 2K users to add. Are there any Perl (C) scripts for adding big amount of users? Something like ./vaddscript users.dat, where users.dat consists of username and password:   [EMAIL PROTECTED]  pass1 [EMAIL PROTECTED]  pass2 ... etc.   Thank you, Roman
