Title: Zephyr File System Demo

Description:

Demonstrates basic file and dir operations using the Zephyr file system.
--------------------------------------------------------------------------------

Building and Running Project:

While this demo uses RAM to emulate storage, it can be tested using QEMU.

Following command will build it for running on QEMU:

    make qemu

--------------------------------------------------------------------------------

Troubleshooting:

Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:

    make clean          # discard results of previous builds
                        # but keep existing configuration info
or
    make pristine       # discard results of previous builds
                        # and restore pre-defined configuration info
