ssh_config

# IdentityFile magic, should be placed at very end of file.
# Allows easier management of many ssh keys without having
# to repeatedly fiddle with ~/.ssh/config. If it's not clear
# you set up your keys as id_rsa_username@host.example.com
# substituting ANY for either the username or hostname if
# desired.
