-#=================================================
-
-# This script is meant to be run by GitHub Actions
-# The YunoHost-Apps organisation offers a template Action to run this script periodically
-# Since each app is different, maintainers can adapt its contents so as to perform
-# automatic actions when a new upstream release is detected.
-
-#=================================================
-# FETCHING LATEST RELEASE AND ITS ASSETS
-#=================================================
-
-# Fetching information
-current_version=$(cat manifest.json | jq -j '.version|split("~")[0]')
-repo=$(cat manifest.json | jq -j '.upstream.code|split("https://github.com/")[1]')
-# Some jq magic is needed, because the latest upstream release is not always the latest version (e.g. security patches for older versions)
-version=$(curl --silent "https://api.github.com/repos/$repo/releases" | jq -r '.[] | select( .prerelease != true ) | .tag_name' | sort -V | tail -1)
-asset_url=$(curl --silent "https://api.github.com/repos/$repo/releases" | jq -r '.[] | select(.tag_name=="'$version'").tarball_url')
-
-# Later down the script, we assume the version has only digits and dots
-# Sometimes the release name starts with a "v", so let's filter it out.
-# You may need more tweaks here if the upstream repository has different naming conventions.
-if [[ ${version:0:1} == "v" || ${version:0:1} == "V" ]]; then
-	version=${version:1}
-fi
-
-# Setting up the environment variables
-echo "Current version: $current_version"
-echo "Latest release from upstream: $version"
-echo "VERSION=$version" >> $GITHUB_ENV
-echo "REPO=$repo" >> $GITHUB_ENV
-# For the time being, let's assume the script will fail
-echo "PROCEED=false" >> $GITHUB_ENV
-
-# Proceed only if the retrieved version is greater than the current one
-if ! dpkg --compare-versions "$current_version" "lt" "$version" ; then

-
-#=================================================
-# UPDATE SOURCE FILES
-#=================================================

-# Here is an example for Grav, it has to be adapted in accordance with how the upstream releases look like.
