# Note: Mutt has a large number of non-upstream patches available for
# it, some of which conflict with each other. These patches are also
# not kept up-to-date when new versions of mutt (occasionally) come
# out.  To reduce Homebrew's maintenance burden, new patches are not
# being accepted for this formula. Mutt power-users are encouraged to
# copy the formula and modify it locally, adding needed patches.
