Creating many user folders

I need to create about 1600 user folders for the school I work at. I have an idea on how to do it but I’m don’t know the ins and outs of batch files. How do I get MD and RMTSHARE to use a text file of users? How does the %(variable) connect to the user names in the text file?
Or Does anyone have a batch file to make this painful operation a breeze?
