"  ~/.vim/syntax/tmux.vim).
" - Make the filetype recognisable by adding the following to filetype.vim
"   (~/.vim/filetype.vim):
"
"	augroup filetypedetect
"		au BufNewFile,BufRead .tmux.conf*,tmux.conf* setf tmux
"	augroup END
"
" - Switch on syntax highlighting by adding "syntax enable" to .vimrc.
