:-)The problem is that do do anything useful with nmh you have to
run the same command thousands of times, each having to do a readdir(). This
is a design flow and an abuse of the operating system. The nmh "commands"
should all be part of the same executable. This elementary design
principle was made very clear to Stock Gaines and to me during several
meetings in 1976. We should have listened more carefully.:-)
