Are there any known workarounds?  I can't seem to figure out any way  
to put the string $abc into a document

\$var didn't work
$$var didn't work

$ isn't a standard html entity - its a 'special character' and not  
widely supported
&dollar; is on some spec sheets, but i haven't found a browser that  
shows it
&#036; is the equiv, but Petal seems to parse  it as a $ for  
interpolation ( so $a works, but $a[a]* doesn't )
