#!/bin/bash
# Save this file as ~/.config/yadm/bootstrap and make it executable. It expects
# environment variable `source` with a name of shell script to execute.
# `source` can be relative to ~/.config/yadm/ or full path.
#
# Usage:
# source=install yadm bootstrap
# or
# source=~/.config/yadm/install yadm bootstrap
#
# where `~/.config/yadm/install` can be like this:
#
# [[ ! $(type -t install) = 'function' ]] && echo "Usage: source=$(basename "$0") yadm bootstrap" && exit 1
#
# confirm yes 'softwareupdate --agree-to-license --install --all' "$(info 'Install ' warning 'OSX updates')"
# install 'brew' '/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"'
#
# brew bundle --global
