# WARNING! CHECK WITH YOUR ADMINSTRATOR'S SOFTWARE INSTALLATION POLICY BEFORE RUNNING THIS SCRIPT!
#  My webhost is cool with letting me do this, but yours might not be. YMMV!
# NOTE: This script does not install ncurses. You might want todo that if you don't have it.
# NOTE: export variables to .bash_profile NOT .bashrc if you are using SSH
# TODO: What if I need to upgrade the softwares?
# UPDATE: Made some modifications that will be the format in the future for installation scripts.
# WARNING! Be sure to update the upgrade variables for your computers needs!

# Make the directories
cd ~
mkdir local
mkdir temp
DIR=$HOME/local

# Export
# NOTE: These variables were set for the DIR directory.
# 	If you use the default values or use a differen DIR,
#	CHANGE THESE VARIABLES! It's very important!
# Note: export to .bash_profile NOT .bashrc
# TODO: Why not use tee commands here?
