# Update Nextcloud apps from latest git master
# For local development environment
# Use from Nextcloud server folder with `./build/update-apps.sh`
#
# It automatically:
# - goes through all apps which are not shipped via server
# - shows the app name in bold and uses whitespace for separation
# - changes to master/main and pulls quietly
# - shows the 3 most recent commits for context
# - removes branches merged into master/main
# - … could even do the build steps if they are consistent for the apps (like `make`)
