<wash-html></wash-html>

Provided by module: Tags: HTML washer

This tag is mostly useful for turning user freetext input from a form into HTML intelligently, by turning sections of the text separated by more than one newline into paragraphs, filtering out or explicitly allowing some HTML tags in the input and creating <a>anchor-links</a> out of potential www-addresses.
