# Update OMZ
# Jonathan Dahan <jonathan@jedahan.com>

# There are two options that can be added to your zshrc
#
# If upstream is a branch other than origin, add
#
#   zstyle ':omz:function:update-omz' upstream 'my-upstream-branch'
#
# To automatically commit from upstream, add
#
#   zstyle ':omz:function:update-omz' auto-commit 'yes'
#
# If you really need auto-updating and do not care about losing data, try
#
#   ( [ ! -f ~/.omz-update ] || [ ~/.omz-update(Nmh+6) ] ) && update-omz && touch ~/.omz-update
