Symlink Packages/Installed Packages:
- Quit ST3
- Clone ST3 repos e.g. ~/src/sublime-text-3
cd ~/Library/Application\ Support/Sublime\ Text\ 3
mv Installed\ Packages Installed\ Packages-17062013
mv Packages Packages-17062013
ln -s /Users/newtriks/src/sublime-text-3/Installed\ Packages ./Installed\ Packages
ln -s /Users/newtriks/src/sublime-text-3/Packages Packages
From then on, any pref changes or updates to packages can then be committed to a central repos.
