# In the GTK version you could make updates by downloading new versions of
# the files from the GIT repository. But it's not an easy thing to set up
# seamlessly for the user. IK because similar system is already in place
# for the Blender-Organizer.
# This system will be somewhat simplified in the UI side of things. But a
# tiny bit more complex from the underliying system. For example. In the old
# release there was no notification of the update.
# So this function here will check for updates.
# Now I have no idea how to implement update notifications. And whether I
# should in the first place. In the old update system I had often made
# easy to fix mistakes. But I was relying a little bit on the fact that
# people don't see immediatly that the update is available. Which I could
# use to fix all the mistakes I found without calling a whole another
# version. Maybe it's a good thing here too.
# I think that since VCStudio Project-Manager is going to be ran as a kind
# of launcher thingy... People will more often use the VCStudio it self and
# rearly the launcher. And so, some kind of automatic update check could be
# done. And no nasty notification. Just a number on the update icon.
# Now to make it work. I need to separate the reading of network to a separate
# python file. update_request.py . That I gonna run as a subprocess to this
# file.
# The updating it self will have to be confirmed by the user. For which will
# need a UI layer. pm_updateLayer.py and a update download file for actually
# donloading and saving those files. update_download.py
# So let's start already.
