---- Upgrading NRG ----

- Before you upgrade, you may want to create copies of your 
NRG install and NRG web site 

     cd /usr/local/
     mkdir nrg.SAVE  # maybe as root
     chown yourlogin nrg.SAVE # maybe as root
     cd nrg
     tar -cf - * | (cd ../nrg.SAVE; tar -xpf -)  # as your login

     cd /usr/local/web/html
     mkdir nrg.SAVE  # maybe as root
     chown yourlogin nrg.SAVE # maybe as root
     tar -cf - * | (cd ../nrg.SAVE; tar -xpf -) # as your login

which you can use to quickly un-do any unexpected changes of 
upgrading:
     
     cd /usr/local/
     rm -rf nrg
     mv nrg.SAVE nrg

     cd /usr/local/web/html
     rm -rf nrg
     mv nrg.SAVE nrg

- You can down-grade to the previous versions of NRG by doing
"make install" in the previous version's source directory.

- If you are upgrading an existing NRG install and have
not changed any of the templates or bin scripts, then do
"make install" and inspect the following new files which may
contain necessary changes in the default NRG configuration:

     Makefile.NEW
     Default.conf.NEW
     NRG.mconf.NEW
