Well, this is only a marginal improvement over what you say above:

[ -n "$VERBOSE" ] && echo "$0: debug output"

This way you can turn on all the debug output by assigning something
to VERBOSE, and turn it off again by unsetting VERBOSE or assigning
it an empty string.

Another thing you can do instead of (or in addition to) echo is logger:

[ -n "$LOGGING" ] && logger -p daemon.notice "$0:  debug output"

puts messages in syslog system instead of on console.

cheerio,
