bash script fake standard in - easy for linux guru

I'm trying to automate some cvs tasks that are taking too much of my time. I need to create cvs users from a script where I pass the script the password like: myScript newusername newpassword and that script must, in turn, run: cvs passwd =a newusername when this prompts for password like passwd does New Password: Then the script should send newpassword on STDIN. Should just be a couple minutes of work for a bash scripting guru. thanks. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
