FYI: PatternTransformer, deserves some publicity I think...

[Bertrand Delacretaz]

I just had a look at the PatternTransformer and its samples, and 
although there has been almost no mention of it on the lists it looks 
very interesting for free-form parsing or enhancement of text (like 
adding links based on text patterns).

For example, it can easily map text such as
  Here is a link in the middle of plain text, http://www.perdu.com
To
  Here is a link in the middle of plain text,  <a 
href="http://www.perdu.com";>http://www.perdu.com</a>

Thanks Stephan for this! I know you have something more sophisticated 
in mind, but this looks very useful already.
