" XXX This file is in need of a new maintainer, Debian VIM Maintainers maintain
"     it only because patches have been submitted for it by Debian users and the
"     former maintainer was MIA (Missing In Action), taking over its
"     maintenance was thus the only way to include those patches.
"     If you care about this file, and have time to maintain it please do so!

" XXX outdated comment
" This file covers mutt version 1.4.2.1i

" For version 5.x: Clear all syntax items
