-# update-from-upstream.zsh
-#
-# This script updates the Oh My Zsh version of the zsh-history-substring-search
-# plugin from the independent upstream repo. This is to be run by OMZ developers
-# when they want to pull in new changes from upstream to OMZ. It is not run
-# during normal use of the plugin.
-#
-# The official upstream repo is zsh-users/zsh-history-substring-search
-# https://github.com/zsh-users/zsh-history-substring-search
-#
-# This is a zsh script, not a function. Call it with `zsh update-from-upstream.zsh`
-# from the command line, running it from within the plugin directory.
-#
-# You can set the environment variable REPO_PATH to point it at an upstream
-# repo you have already prepared. Otherwise, it will do a clean checkout of
-# upstream's HEAD to a temporary local repo and use that.
-
-
-# Just bail on any error so we don't have to do extra checking.
-# This is a developer-use script, so terse output like that should
-# be fine.

-$thin_line
-
-What you are looking at now is Oh My Zsh's repackaging of zsh-history-substring-search 
-as an OMZ module inside the Oh My Zsh distribution.
-
-The upstream repo, $UPSTREAM_REPO, can be found on GitHub at 
-$upstream_github_url.
-
-This downstream copy was last updated from the following upstream commit:
-
-  SHA:          $upstream_sha
-  Commit date:  $upstream_commit_date
-
-Everything above this section is a copy of the original upstream's README, so things
-may differ slightly when you're using this inside OMZ. In particular, you do not
-need to set up key bindings for the up and down arrows yourself in \`~/.zshrc\`; the OMZ 
-plugin does that for you. You may still want to set up additional emacs- or vi-specific
-bindings as mentioned above.
