#!/usr/bin/env bash
#
# install.sh - installation for my dotfiles
#
# SYNTAX
#
#	./install.sh [-q|--quiet]
#
# DESCRIPTION
#
# 	Installs all my dotfiles on your current user's working directory.
#
# 	This script would not only prepare my dotfiles on your home directory,
# 	since ZSH plugins and necessary packages will be installed too whether
#	there is a valid package manager installed on your current machine.
#
# 	To prevent errors, installation would ask you to create a backup for your
#	old dotfiles, which will be stored at current dotfiles path (see exports).
#
#	Relative to configuration, you can modify exports file to adjust some settings
#	like dotfiles path. It is important to notice that any changes you make are not
#	considered and can provoke errors, so please modify exports by your own risk!
#
# ARGUMENTS
#
#	[-q | --quiet]			Execute installation with no output messages at
#							current shell. This was included to offer a way
#							to use this command at bash scripts. You should
#							know that dotfiles backup would be done if this
#							option has been set to current command
