 if the code is particularly long (greater than 2,000 lines) then you
might wish to look at java2py.py and use it as the basis to write a
"dumb" assistant in doing much of the code-conversion:

http://pyjamas.svn.sourceforge.net/viewvc/pyjamas/trunk/contrib/java2py.py?revision=1572&content-type=text%2Fplain

 this program is _not_ parser-based (yacc, ply, oMeta2) it is line-
based and state-based.  specific assumptions are made about the code
layout (braces in K&R formatting style for example) and, thanks to the
high code-quality of the code it was used to translate (GWT) this was
not in the slightest bit a problem.

 so, _in combination with a code-cleaner_ such as "indent", which
regularises the formatting of whatever god-awful-looking perl you want
to translate, the approach indicated by java2py.py will save you a lot
of time and mistakes.

 think about it, even if the code you want to translate is 500 lines.
that's 500+ lines you need to rewrite, whereas something as simple as
267 lines of python could help automate that process of conversion.
