For example:
I want
!quote
if{$message(true), print>"Thanks $username! I've saved your $message to the quote database!", @writeline@ > db.txt}
Elseif{$message(null), print>"Usage: To add a quote type: !quote some-quote-here"}
So far, I can get away with this in other bots if I put the two commands on different lines and they leave the !quote blank.
BUT if they actually include something, the help text still displays as well as the success command.
