# This script sets up a new account. As this is the dotfiles.core
# installer, only things which apply to every account are done here.
#
# This installer assumes that the dotfiles.core repository has been
# cloned into the $HOME directory under the name 'dotfiles.core'. It
# should be cloned and run this way for every new user.


# Messages passed to the user by this script are in 8-char columns.
