/* Package action provides implementations for every Glide command.

This is not a general-purpose library. It is the main flow controller for Glide.

The main glide package acts as a Facade, with this package providing the
implementation. This package should know nothing of the command line flags or
runtime characteristics. However, this package is allowed to control the flow
of the application, including termination. So actions may call `msg.Die()` to
immediately stop execution of the program.

In general, actions are not required to function as library functions, nor as
concurrency-safe functions.
