[Distutils] Setuptools reindenting reST documentation?

Hi there, I have a reST documentation containing something like that blablabla:: foo foo foo foo foo foo used as long_description. After building the egg the PKG-INFO file contains the text with the same indentation level. I came across this issue because rst2html.py did not complain before building the egg but a later conversion of the reST document taken from the PKG-INFO produced serveral errors. Why is setuptools doing that? Andreas
