+Setup and retrieve HTTPS and SSH credentials for use with 'git'
+and other services. For HTTPS remotes the package interfaces
+the 'git-credential' utility which 'git' uses to store HTTP
+usernames and passwords. For SSH remotes we provide convenient
+functions to find or generate appropriate SSH keys. The package
+both helps the user to setup a local git installation, and also
+provides a back-end for git/ssh client libraries to authenticate
+with existing user credentials.

+Simple git client for R based on 'libgit2' with support for SSH
+and HTTPS remotes. All functions in 'gert' use basic R
+data types (such as vectors and data-frames) for their arguments
+and return values. User credentials are shared with
+command line 'git' through the git-credential store and ssh keys
+stored on disk or ssh-agent.
