I thought that the pelog script environment was really bare (i.e. root's
environment) and that this sort of information (i.e. node number) would
be passed in as an argument.
May just be some lag in the documentation, though. Appendix G, section
1 indicates that "For all scripts, the environment passed to the script
is empty." I don't know the pros/cons of doing arguments vs.

Should be good. Thanks for all your fine work...
