Very simple filter that enables the strike-through of text.

Like this: 

%%(color:black)This text stricken

Installation is very easy: 

a) Edit {{filters.xml}} - in WEB-INF/classes and add

{{ <filter> \\
  </filter> }} \\

And put the jar file Strikethrough.jar in the WEB-INF/lib. 

To use the Strike through: delimiters are {{_( }}  and  {{ )_ }}

this is a _(good)_ bad idea. 


Alternative, you can use %~%strike like %%strike here %%.
