+mac-ssh-askpass
+===============
+
+An Aqua_-based passphrase dialogue for use not only with OpenSSh_.
+
+``mac-ssh-askpass`` asks for a passphrase on macOS, using the graphical
+user interface. It conforms to the so-called `SSh Askpass Protocol`_.
+
+I wrote this because I was looking for something simple,
+but couldn't find anything.
+
+
+.. _Aqua: https://en.wikipedia.org/wiki/Aqua_(user_interface)
+
+.. _OpenSSh: https://www.openssh.com/
+
+.. _`SSh Askpass Protocol`: https://man.openbsd.org/ssh-add
