+Handle gitea actions runners.
+
+This helper aims to make easier to create, start, stop and delete gitea actions runners which run in docker containers.

+    - start     Starts an existing runner.
+    - stop      Stops an existing runner.
+    - delete    Deletes an existing runner.
+
+Some actions need parameters.
+Parameters of action "create":
+    - \$1       The name of the runner to create.
+
+Parameters of action "start":
+    - \$1       The name of the runner to start.
+
+Parameters of action "stop":
+    - \$1       The name of the runner to stop.
+
+Parameters of action "delete":
+    - \$1       The name of the runner to delete.
