+Script to print all the available environments in Isaac Lab.
+
+The script iterates over all registered environments and stores the details in a table.
+It prints the name of the environment, the entry point and the config file.
+
+All the environments are registered in the `isaaclab_tasks` extension. They start
+with `Isaac` in their name.
