#!/bin/bash
#
# A basic script to retrieve and install packages to a local directory
# (e.g. in a users home space)
#
# We assume packages can be compiled in the "standard" way using
# "configure" and "make"
#
# A better alternative is to use your inbuilt package manager to install things
# e.g.
# Debian/Ubuntu:
# sudo apt-get install package_name
# Fedora/Red Hat/CentOS:
# sudo yum install package_name
# OpenSUSE:
# zypper install package_name
# MacPorts:
# sudo port install package_name
# Homebrew:
# brew install package_name
