# Each line is passed as the argument(s) to `homeshick clone`.
# Lines starting with '#' will be ignored.
# Git must be able to access these repositories, if you put private
# repositories on the list be sure to have access configured.
# You can CTRL-Z, do it, and `fg` to come back and complete the process.
#
# If you remove or comment a line that castle will NOT be installed.
# However, if you remove or comment everything, the script will be aborted.
