Passing the private key passphrase

I'm trying to completely script a transfer using SFTP using the command line console. I've gotten to the point where everything works except when it gets to the point of authenticating, it wants the private key passphrase. No surprise there. But, I can't seem to find any documentation about how to send the passphrase natively within WinSCP (eg: in an INI file) or doing it through Pagaent. If I use the GUI, it's fine and I get connected to the remote host. I'm aware that having the passphrase in a text file is a bad idea, but humor me for now. Any ideas?

Here's my log output:

prompt for passphrase

Did the FAQ help? I have the same issue and cannot figure out how to automate the supply of the passphrase.

Maybe we should not use a passphrase when implementing automation of SFTP?
