r-cran-askpass - 1.1-2 main

Cross-platform utilities for prompting the user for credentials or a
passphrase, for example to authenticate with a server or read a protected key.
Includes native programs for MacOS and Windows, hence no 'tcltk' is required.
Password entry can be invoked in two different ways: directly from R via the
askpass() function, or indirectly as password-entry back-end for 'ssh-agent'
or 'git-credential' via the SSH_ASKPASS and GIT_ASKPASS environment variables.
Thereby the user can be prompted for credentials or a passphrase if needed
when R calls out to git or ssh.
