# On Windows, Twisted >= 12.2.0 has a dependency on pywin32.
# Since pywin32 can only be installed manually, we fall back to
# requiring earlier versions of Twisted and Nevow if it is not
# already installed.
# <https://tahoe-lafs.org/trac/tahoe-lafs/ticket/2028>
#
# When the fallback is used we also need to work around the fact
# that Nevow imports itself when building, which causes Twisted
# and zope.interface to be imported; therefore, we need to set
# setup_requires to make sure that the versions of Twisted and
# zope.interface used at build time satisfy Nevow's requirements.
#
# In cases where this fallback isn't needed, we prefer Nevow >= 0.11.1
# which can be installed using pip, and Twisted >= 13.0.0 which
# Nevow 0.11.1 depends on. In this case we should *not* use the
# setup_requires hack, because if we do then the build will break
# when Twisted < 13.0.0 is already installed (even though it could
# have succeeded by building a later version under support/ ).
