First, backup /etc/passwd, /etc/shadow, /etc/group :)

I would suggest to just create such a script. It's easy. Imagine,
you have a file with a line for each user like
user1 pass1
user2 pass2
and so on. pass shouldn't have spaces I guess. Call it i.e.
new_users. Well, then create a bash script like:

#!/bin/bash
#This is an untested example
while read a b ; do
   echo -n user: $a
   useradd -m $USERADDOPTS $a
   echo "$a:$b" | chpasswd
   echo " OK"
done < new_users

USERADDOPTS can carry additionally parameters (try 
useradd --help).

(put the code in a file, chmod +x it, execute it. Feel free to
add something. Please check it before using it :). Try it with
one or two accounts, adjust it, and finally just use it :)).

I don't recommend to edit /etc/passwd or /etc/shadow directly at
all. There are already tools build for that that care about
security, safeness, races, tmpfiles and so on.

It's GNU/Linux, so just use it :)

oki,

Steffen
