Patch attached for webob ebuild that adds a doc USE flag to optionally build and install webob documentation.
Created attachment 259935 [details, diff] Ebuild patch
docs/_build directory seems to contain already built documentation, so it should suffice to install it without using sphinx.
I don't think it has _static/ though.
Fixed in dev-python/webob-1.0.5.
Unfortunately documentation is no longer available in dev-python/webob-1.0.6 tarball.
