I tried this:

print context(_.None, _)

and got this error:

Error Type: NameError
Error Value: _

So I tried context.id(_.None,_) and got the same.  So I tried 'print
context(None,_)', with the same error resulting.  Finally, I have tried:

print context(None,)

and got

Error Type: KeyError
Error Value: standard_html_header

This last error at least seems like it's on the right track as it is parsing
through the text of the file.  What's going wrong, any idea?

thanks
