or source utils.sh (in the plugin-scripts dir of the plugins distro) so 
that you can say

if [ $1 = $STATE_OK ] ; then
  echo | printf "OK"
  exit $STATE_OK
else
  echo | printf foo
  exit $STATE_CRITICAL
fi

The moral of the story is that the plugin developers want to maximise 
reuse and minimise code duplication by factoring out common definitions 
(common constants such as return code values; default timeouts etc)  for 
plugin authors to take advantage of (the Perl equivalent is utils.pm).

Anyone writing their own plugins should have a look at the source of the 
standard plugins.

continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
