# This is the ZSH completion file for Twisted commands. It calls the current
# command-line with the special "--_shell-completion" option which is handled
# by twisted.python.usage. t.p.usage then generates zsh code on stdout to
# handle the completions for this particular command-line.
#
# 3rd parties that wish to provide zsh completion for commands that
# use t.p.usage may copy this file and change the first line to reference
# the name(s) of their command(s).
#
# This file is included in the official Zsh distribution as
# Completion/Unix/Command/_twisted

# redirect stderr to /dev/null otherwise deprecation warnings may get puked all
# over the user's terminal if completing options for a deprecated command.
# Redirect stderr to a file to debug errors.
