+This script is intended to fix the common problem where npm users
+are required to use sudo to install global packages.
+
+It will backup a list of your installed packages remove all but npm,
+then create a local directory, configure node to use this for global installs
+whilst also fixing permissions on the .npm dir before, reinstalling the old packages.
