Shared WPKGs in use by both Chemistry and Maths

Environment variables
=====================
We expect that you will have set the following environment variables:

1. WPKGJS  
Full UNC path to 32-bit wpkg.js
1. WPKGJS64  
Full UNC path to 64-bit wpkg64.js
1. WPKGINSTITUTION  
Agreed-upon code your institution (see below)
1. WPKGSOFTWARE  
Full UNC path to your local institution's store of software
1. SOFTWARE  
(Optional but recommended) Should be set to the same value as WPKGSOFTWARE, for legacy purposes
1. WPKGLOGDIR  
Directory in which software installer logs are to be kept

The included wpkg wrapper script will look in HKLM\SOFWARE\WPKG\vars and set environment variables for all keys of type REG_SZ, so you could e.g.

reg add HKLM\SOFTWARE\WPKG\vars /v WPKGINSTITUTION /t REG_SZ /d chemistry

Institute codes
==============
1. chemistry  
Department of Chemistry
2. maths  
Faculty of Mathematics

Repository layout
================

\packages - directory with multiple xml files, each of corresponds to an individual WPKG package definition
