Well, I'm all for giving JTidy a try, in testing it seems to work okay.

One question- what is the best way to pipe the output through Tidy when 
merging your templates?  It takes an InputStream and OutputStream. (My 
HTML output  is aways a file on disk.) Velocity's template.merge() takes 
a BufferedWriter.  It is almost like I'd want a gender changer (to lack 
a better term) to convert the BufferedWriter passed into 
template.merge() into an InputStream that could be passed into Tidy.

The only option I can think of involves a two stage process of writing 
Velocity's output to a string in memory or a temp file, neither of which 
I like.  I'd like to just hook the streams up together and let it go.  
Any ideas?

Thanks,
Brian
