# Targets:
# - "depend" retrieves the Go packages needed to run the linter and tests
# - "lint" runs the linter
# - "test" runs the tests
# - "release" creates a new release commit, tags the commit and pushes the tag to GitHub.
#   "release" also updates the examples and plugins repo and pushes the updates to GitHub.
#
# Meta targets:
# - "all" is the default target, it runs "lint" and "test"
