# Python allows reloading modules on the fly, which allows us to do live upgrades.
# The only caveat to this is that you have to reload in the dependency order.
#
# Thus is module A depends on B and we don't reload B before A, when A is reloaded
# it will still have a reference to the old B. Thus we hard-code the dependency
# order of the various Package Control modules so they get reloaded properly.
#
# There are solutions for doing this all programatically, but this is much easier
# to understand.
