Why should someone start to rewrite his collection of regexp search/ 
replace-strings when there is still a little hope that he can  
continue using them with the other program? Honestly, I really hoped  
that someone just says »right, you can also set this option there«. I  
didn't expect the applications to be so ... narrow-minded ;o)
