Include generated configs by adding to your ~/.ssh/config:

Include *.config

To include generated aliases and allow autocomplete for ssh add to your .bash_profile:

# aliases generated from Zone API
for f in ~/*.alias; do source "$f"; done
alias umount_sshfs=\'for f in ~/sshfs/*; do umount "$f"; done\'

# *.config files generated from Zone API
complete -W "$(echo `cat ~/.ssh/config ~/.ssh/*.config | grep -E \'^Host\' | cut -d" " -f2- | tr " " "\n" | grep -v "*" | sort | uniq`;)" ssh
