[Cook] Multiple independent targets of a recipe

[Fredrick Paul Eisele]

Yes.
What you are looking for is an implict (template) recipe.
When cook makes its first pass it expands the implicit recipes into
as many recipes as there are matching targets.
In other words you write something that looks similar to your second example
and cook generates the two rules (invisibly) as in your first example.

The implicit rule ...

target.%1: <inputs>
{
  blah
}

The %1 is a wildcard parameter.
Look in the cook user's guide for details in writing the patterns.
