-# * On Linux we need at least Twisted 10.1.0 for inotify support
-# used by the drop-upload frontend.
-# * We also need Twisted 10.1.0 for the FTP frontend in order for
-# Twisted's FTP server to support asynchronous close.
-# * The SFTP frontend depends on Twisted 11.0.0 to fix the SSH server
-# rekeying bug <https://twistedmatrix.com/trac/ticket/4395>
-# * The FTP frontend depends on Twisted >= 11.1.0 for
-# filepath.Permissions
-#
-# 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/ ).
