/** @file
EFI Shell Interface protocol from EDK shell (no spec).
Shell Interface - additional information (over image_info) provided
to an application started by the shell.
ConIo - provides a file style interface to the console. Note that the
ConOut & ConIn interfaces in the system table will work as well, and both
all will be redirected to a file if needed on a command line
The shell interface's and data (including ConIo) are only valid during
the applications Entry Point. Once the application returns from it's
entry point the data is freed by the invoking shell.
