# Splitting the dependencies for Windows and non-Windows helps to fix

# * 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.

#
# 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.
