# We also require zope.interface, but some older versions of setuptools such
# as setuptools v0.6a9 don't handle the "." in its name correctly, and anyway
# people have to manually install Twisted before using our automatic
# dependency resolution, and they have to manually install zope.interface in
# order to install Twisted.

# Ubuntu Dapper includes nevow-0.6.0 and twisted-2.2.0, both of which work.
# However, setuptools doesn't know about them, so our install_requires=
# dependency upon nevow causes our 'build-auto-deps' step to try and build the
# latest version (nevow-0.9.18), which *doesn't* work with twisted-2.2.0 . To
# work around this, remove nevow from our dependency list if we detect that
# we've got nevow-0.6.0 installed. This will allow build-auto-deps (and everything
# else) to work on dapper systems that have the python-nevow package
# installed, and shouldn't hurt any other systems. Dapper systems *without*
# python-nevow will try to build it (and will fail unless they also have a
# newer version of Twisted installed).
