Maybe now...?  There could be "user defined actions"... in addition to
"restart", "stop", et. al. .

Yep.

And even worse...

   start = "/bin/foo --message 'Monit Rulez!'"

has to work and even...

   start = "/bin/foo --message 'I like LaTeX umlaute "a "o "u'"

or...

   start = "/bin/foo\ bar"

But the multi line code needs start conditions. Otherwise it would
complain about "echo" being an unknown token.  And it really not
complicated, it makes it IMO even more readable and maintainable. (-:
You can see much better where you are in a statement or type.

s.o.

Absolutely.

Later... I can try to tidy up the language a bit.  And give you a try
with the programs.  We gonna have maintenance work in our power supply
and network, so it's gonna be difficult for me... that reminds me to
charge the laptop today.

Murphy's law.
