err... 

lynx --source --dump http://example.com/
wget --help
gzip cvf --best ...

etc.

Oh, I was just stating my personal preference! If both options are
possible, it's probably good to have both in examples anyway.

(with comments where appropriate for the alternates I guess...)

I'm more worried about making my templates as much TAL
compliant as possible, because TAL has been quite extensively
tested with WYSIWYG whilst the inline dollar syntax hasn't.

I guess it depends which degree of compatibility you want to achieve
with the tools you're using, and also what syntax is better suited for
the tools you're using.

For example, if you were writing XHTML, id="$id" would be terrible
because '$' is not allowed in XHTML identifier, hence validators would
raise an error.
