Mac OS/X install command line tools

#!/bin/bash
 
# install_cltools.sh
# This script will install Apple Command Line Tools in
# an automated fashion after downloading the install
# dmg from an accessible web server.
 
# This is a webserver from which the installers can be
# downloaded. Unfortunately, Apple has a lame habit
# of only making these utilities available for download
# by logging into their website, so you'll need to
# download them there and then move them onto a web
# server that this script can access. PROTIP: You can
# even use localhost by starting a quick python
# webserver from the ~/Downloads directory on your Mac.
# For example:
# cd ~/Downloads; python -m SimpleHTTPServer 8080
webserver="http://localhost:8080/"
