+# This script manages a release note or its asset with GitHub API v3.
+# It accepts the following parameters:
+#
+# * repo
+# * tag
+# * type (asset or edit)
+# * filename
+# * github_api_token
+# * action (optional, could be upload, overwrite, rename, delete, default to be upload)
+# * extra  (optional, new filename for action 'rename')
+# * create (optional, create a new release if it doesn't exist)
+#
+# Example:
+#
+# # Upload a file as asset. If there is a asset with the same filename, then overwrite it.
+# github-release.sh github_api_token=TOKEN repo=stefanbuck/playground tag=v0.1.0 type=asset filename=./build.zip overwrite=true
+#
+# # Edit a release note with file content
+# github-release.sh github_api_token=TOKEN repo=stefanbuck/playground tag=v0.1.0 type=edit filename=note
