# event_comment
# >= 5.6 needs libevent[>=1.4.12&<2.0] but
# a) we only have 2.0.22 at the time of writing
# b) lots of other stuff needs >=2.0
#
# Options:
#
# 1. Add libevent 1.4.x, imlement the dep as [>=1.4.12&<2.0] and watch the fun
# 2. Us the bundled libevent for MySQL to ensure it's always the right version.
# 3. Add libevent 1.4.x as SLOT=1.4, slot 2.0.x as SLOT=2.0, dep on the 1.4 slot here.
#
# I prefer 3., of course, but I went with 2. for now to be on the safe side.
