### VARIABLES ###

# Please know that this script should be executed as normal user with __sudo__ privileges.

# Pre-requisites to compile Nginx from source
PRE_PACK="gcc make libpcre3-dev zlib1g-dev libssl-dev libgeoip-dev"

# Change the following to whatever the current version.
# You can know the current versino at http://nginx.org
CURRENT_VER="1.6.0"

# Be careful, in choosing this value.
# Valid values are "BINARY", "NULL", "currently_installed_version_number"
# Use "NULL" - If your server hasn't got Nginx now.
# Use "BINARY" - If your server has __already__ got Nginx that was installed using "sudo apt-get install nginx" command.
# Use "currently_installed_version_number" - If your server has already got Nginx that was installed using this script.
PREV_VER="BINARY"

# To disable PageSpeed module...
# Step #1 - set VERSION_PAGESPEED_MODULE="NULL"
# Step #2 - remove the line "--add-module=$HOME/src/ngx_pagespeed-release-${VERSION_PAGESPEED_MODULE}-beta" in CONFIGURE_OPTIONS
VERSION_PAGESPEED_MODULE="1.7.30.1"

# This may change, depending on your requirement.
# The following _may_ fit most use-cases
