Getting rid of notextile elements in Typo

This is actually a Redcloth issue. I'm not really sure why non standard elements such as notextile were spread throughout typo's blogware to begin with but they were wreaking havoc on my w3 validation so I had to get rid of them.

Getting rid of them

The ruby way of doing this:

gsub!('\/?notextile>', '')

And for cryptic comparison, let's show perl:

find . -iname "*" -exec perl -pi -e 's/<\/?notextile>//ig;' '{}' \;

How about sed:

find /path -exec sed -ir 's/<\/*notextile>//g' {} \;
