In addition to that, its also possible though more work to disable
echo but to emit the command line after a command fails. Not only do
you get the nice output for commands that succeed, and error output
from say gcc or ld, but you also get the complete command line for the
command that caused the issue. The jam build system we use does this
sort of thing and it works well. It is a very rare moment that you
need more information than that.
