# -----------------------------------------------------------------
# Compatible with ipset versions: 6+
# Tested with ipset versions:
# 6.24, 6.27
# -----------------------------------------------------------------
# Requirements:
#
# bash v4 or greater.
#
# The bash completion package version 2.0 or greater is recommended.
# http://bash-completion.alioth.debian.org/
# Older version are not supported.
#
# If the package is not available, things might not be so reliable.
# Also the colon (if there) is removed from COMP_WORDBREAKS.
# This alteration is globally, which might affect other completions,
# if they don't take care of it themselves.
#
# -----------------------------------------------------------------
# Installation (quote from bash-completion README):
#
# Install it in one of the directories pointed to by
# bash-completion's pkgconfig file variables. There are two
# alternatives: the recommended one is 'completionsdir' (get it with
# "pkg-config --variable=completionsdir bash-completion") from which
# completions are loaded on demand based on invoked commands' names,
# so be sure to name your completion file accordingly, and to include
# for example symbolic links in case the file provides completions
# for more than one command. The other one which is present for
# backwards compatibility reasons is 'compatdir' (get it with
# "pkg-config --variable=compatdir bash-completion") from which files
# are loaded when bash_completion is loaded.
#
# For packages using GNU autotools the installation can be handled
# for example like this in configure.ac:
#
# PKG_CHECK_VAR(bashcompdir, [bash-completion], [completionsdir], ,
# bashcompdir="${sysconfdir}/bash_completion.d")
# AC_SUBST(bashcompdir)
#
# ...accompanied by this in Makefile.am:
#
# bashcompdir = @bashcompdir@
# dist_bashcomp_DATA = # completion files go here
#
# For cmake we ship the bash-completion-config.cmake and
# bash-completion-config-version.cmake files. Example usage:
#
# find_package(bash-completion)
# if(BASH_COMPLETION_FOUND)
# message(STATUS
# "Using bash completion dir ${BASH_COMPLETION_COMPLETIONSDIR}")
# else()
# set (BASH_COMPLETION_COMPLETIONSDIR "/etc/bash_completion.d")
# message (STATUS
# "Using fallback bash completion dir ${BASH_COMPLETION_COMPLETIONSDIR}")
# endif()
#
# install(FILES your-completion-file DESTINATION
# ${BASH_COMPLETION_COMPLETIONSDIR})
#
# For backwards compatibility it is still possible to put it into
# ~/.bash_completion or /etc/bash_completion.d/.
