Hello, world
#if falseArg
   Shouldn't be here.
#else
   But this should
   -->${stringValue}<--
#fi

#if true
	True1
	${stringValue:-Should not be here}
	${noSuchVar:-Should be here}
	#if trueArg
	  True2
	#else
	  False 1
	#fi
#else
	False 2
	#if true
	  Not expected
	#else
	  Not expected 2
	#fi
#fi
	
This should say no: ${falseArg?yes:no}
This should say yes: ${trueArg?yes:no}

This should say someString: ${trueArg?${stringValue}:}
This should say xxsomeStringxx: ${not_found?${stringValue}:xx${stringValue}xx}

The end.
