I've been toying around with include variables to create easy to use
templates. The last hurdle was making variables optional. so I started
searching for a way. Apparently the conditional markup does not support

For that reason I wrote a (simple) conditional to check if an include
parameter is actually set. I am sharing it with the community through this
way, because I am certain improvements can still be made to it. I hope it
serves some use to someone. Feel free to improve it and add it somewhere on
the pmwiki website.

So without further rambling, the markup to be added to your local config
file to check if an include parameter is set.

$Conditions['includevarset'] = 'substr(\$condparm, 0, 3) != "{\$\$"';
