Development.NSIS.Plugins.EnvVarUpdate

Module for updating environment variables. All functions take either HKLM to modify the variable for the machine, or HKCU to modify for the user.

Warning: If you are modifying PATH, make sure you use a special build of NSIS which can cope with longer strings, or you will corrupt your users path.
