PottyMouth transforms completely unstructured and
untrusted text to valid, nice-looking, completely
safe XHTML. PottyMouth is designed to handle input
text from non-technical, potentially careless, or
malicious users. It produces HTML that is
completely safe, programmatically and visually, to
include on any Web page. You don't need to make
your users read any instructions before they start
typing. They don't even need to know that
PottyMouth is being used.
