Question about ssh-askpass

[Daiki Ueno]

Hello.

I'm new to the list, and I have some questions.

I'd like to use ssh as a subprocess, and I'm looking for a generic way
of passing passphrase. So far as I know, in SSH Communications'
implementation of SSH, ssh invokes ssh-askpass as well as
ssh-add does. Lacking of this is just because of security reason?

Are there any plans to use some kind of readymade option parsing
routine--such as getopt?

Thank you,
