#### Version String Readme ####

    ## Customrc ##

    Create a file at the top level of op-build called 'customrc'
    to specify custom $(OPBUILD_VENDOR), $(OPBUILD_PLATFORM), and $(OPBUILD_VERSION).

    Example:
    #!/bin/sh
    #export OPBUILD_VENDOR=IBM
    #export OPBUILD_PLATFORM=plat-ibm
    #export OPBUILD_VERSION=v-1.0.1

    ## Op-build Commands ##

    # Display subpackage version
    op-build $(package)-version

    # Display entire pnor version
    op-build openpower-pnor-version

    # Force a rebuild of a subpackage version
    op-build $(package)-build-version

    # Force a rebuild of all subpackage versions
    op-build openpower-pnor-build-version-all

    ##  Version String (ASCII) ##

    General:
    $(op-build)\n
    \t$(subpackage0)\n
    \t$(subpackage1)\n
    \0

    ## Version String Details ##

    $(op-build):
    - Clean
        + $(vendor)-$(platform)-$(op-version)
    - Dirty.
        + $(vendor)-$(platform)-$(gitcommit+dirty)
    $(sub-package):
    - Directly upstream, no patches, op-build clean.
        + $(package)-$(version)
    - Directly upstream, no patches, op-build dirty.
        + $(package)-$(version)-$(op-dirty)
    - Directly upstream, op-build patches, op-build clean
        + $(package)-$(version)-$(patch-level)
    - Directly upstream, op-build patches, op-build dirty.
        + $(package)-$(version)-$(op-dirty)-$(patch-level)
    - SITE=local
        + $(package)-site_local-$(user)-$(gitcommit+dirty)

    ## Variable Details ##

    - $(vendor) = $(OPBUILD_VENDOR) or 'open-power'.
    - $(platform) = $(OPBUILD_PLATFORM) or defconfig
        + Order $(OPBUILD_PLATFORM), defconfig
    - $(op-version) = git tag or first 7 characters of commit or $(OPBUILD_VERSION) or 'unknown'.
        + Order $(OPBUILD_VERSION), tag, commit, unknown
    - **$(gitcommit+dirty) = abcd123 or abcd123-dirty or 'unknown'
    - $(version) = git tag or first 7 characters of commit
    - $(user) = `whoami`
    - **$(op-dirty) = opdirty or 'unknown'
    - $(patch-level) = $(first 7 characters of 'sha512sum *.patch | sha512sum')
        + the output of this gives us a quick way to check all the patches with one string

    ** Indicates possible unknown case when source downloaded versus git clone due to git commands required

    cmd> op-build openpower-pnor-version
    === OPENPOWER_PNOR_VERSION ===

    cmd> op-build hostboot-version
    === HOSTBOOT_VERSION ===
        hostboot-3593853-opdirty-99cca2b

    If a version does not already exist, the commands to make one will be run.
    Additionally you can force with op-build $(package)-build-version

    cmd> op-build hostboot-version (or op-build hostboot-build-version)
    === HOSTBOOT_VERSION ===
