A generated file that is addressable by a label is called a *predeclared
output*. There are multiple ways for a rule to introduce a predeclared output:
-* If the rule declares an [`outputs`](lib/globals.html#rule.outputs) dict in its
- call to `rule()`, then each entry in this dict becomes an output. The output's
- label is chosen automatically as specified by the entry, usually by
- substituting into a string template. This is the most common way to define
- outputs.

* The rule can have an attribute of type [`output`](lib/attr.html#output) or
[`output_list`](lib/attr.html#output_list). In this case the user explicitly
chooses the label for the output when they instantiate the rule.
