Actually, $$ is fine. $$$ would probably get evaluated to $ (the first  
escaped, the second removed due to an invalid macro).

You then have to consider the shell, so sticking single quotes around  
it will stop the shell from evaluating the ${sometext} as a variable.

This is all before it even reaches the plugin....
