install.sh

#!/bin/zsh

# Commentary:

# This script installs the pre-requisite softwares that are required for the
# Emacs config to work correctly.

# On Debian based Linux distros like Ubuntu (latest version), it will invoke the
# 'install-for-debian.sh' script and packages are installed with 'apt' or
# 'snap'. If you get permission denied errors, try running the script with
# 'sudo' permissions.

# On Mac, this script will invoke the 'install-for-mac.sh' script and packages
# are installed with 'brew'. If you do not have 'brew' installed, you should do
# that first before running this script.

# This script requires 'zsh' shell and assumes that it is present on your
# system. In my opinion, you should probably think of switching to 'zsh' if you
# haven't already!
