[fetchmail] Piped password or non-interactive password

Hi,

I would like to run fetchmail without any rc files and non interactive to 
collect mail from a pop3 box. The only issue is that it asks for a password. 
I found the following in getpass.c which suggests that I can send the 
password in a pipe. Can anyone tell me how to do this.

/***********************************************************************
  module:       getpass.c
  project:      fetchmail
  programmer:   Carl Harris, ceharris(_at_)mal(_dot_)com
  description:  getpass() replacement which allows for long passwords.
                This version hacked by Wilfred Teiken, allowing the
                password to be piped to fetchmail.
