# My custom theme:
#   - single line
#   - quite simple by default: user@host:$PWD
#   - green for local shell as non root
#   - red for ssh shell as non root
#   - magenta for root sessions
#   - prefix with remote address for ssh shells
#   - prefix to detect docker containers or chroot
#   - git plugin to display current branch and status

# git plugin
