Module: Beaker::DSL::Wrappers

Included in:
Beaker::DSL, PSWindows::Exec
Defined in:
lib/beaker/dsl/wrappers.rb

Overview

These are wrappers to equivalent Command objects so that command line actions are executed within an appropriate and configurable environment.

I find most of these adapters of suspicious value and have deprecated many of them.
