 If template has a `name` variable, it is used instead of template
 filename. High-level task names are:
 
+*      `clean-<name variable or template filename>`
+*      `build-<name variable or template filename>`
 *      `clean-<name variable or template filename>-<build name>`
 *      `build-<name variable or template filename>-<build name>`
 
-Note that there is no out-of-the-box single task to run all builds
-defined in one template.

 ## Supported Packer configurations:
 *	Builders:
 	*	`virtualbox-iso` and `virtualbox-ovf`.
