# Spec 

###
Companion object Spec

#### trait Spec extends AnyRef

This trait works together with others in scala.tools.cmd to allow declaratively specifying a command line program, with many attendant benefits. See scala.tools.cmd.DemoSpec for an example.

   Deprecated

     (Since version 2.12.16) Use `formatString.format(value)` instead of `value.formatted(formatString)`, or use the `f""` string interpolator. In Java 15 and later, `formatted` resolves to the new method in String which has reversed parameters.
