What is the best syntax highlighter that can be used to show code on a site?
I'm looking for something like this:

http://www.digitalcoding.com/tools/html-beautifier.html

After you beautify the html it appears in a nice syntax highlighter. I can't tell what they are using and don't know what the term is for these "embeddable syntax highlighters" that you see on many programming sites nowadays.

ah never mind about not knowing what they are using, I clicked the question mark symbol and it looks like they are using this: `http://alexgorbatchev.com/SyntaxHighlighter/`

so now the question is, are there any better ones out there?
