Linux Creating new users using a text file as imput (using only shell script and/or awk)

I need somebody who could help with an exercise.

You have a text file called users.txt with this info inside:

users.txt:
Code:
user1:1234:/home/homedir1 ;

user2:1234:/home/homedir2 ;

user3:1234:/home/homedir3 ;

user4:1234:/home/homedir4 ;

The script should create an user using the first word of each line, the second word of each line will be used as password, and the third one as the home directory.

I would be very grateful If anybody can point me in the right direction
