#   NOTICE: This RPM specification is _very_ special, because it is
#   used both for bootstrapping OpenPKG with its RPM and for regular
#   builds of RPM in order to upgrade an existing installation. For this
#   it has to interact correctly with the "openpkg.boot" script. See
#   this companion script for details, but do not touch anything here
#   until you are 100% sure about what you are doing. In short: This
#   script is allowed to use only a very restricted subset of the RPM
#   functionality!

#   BUILD REQUIREMENTS:
#   o any sh(1)
#   o any tar(1)
#   o any make(1)
#   o any cc(1)

%description
    This is the bootstrap package for the RPM-based Unix Software
    Package Hierarchy OpenPKG. The RedHat Package Manager (RPM) is a
    sophisticated and portable package manager for Unix platforms,
    which supports the automated building, installation, management and
    deinstallation of Unix software. Originally RPM is designed and
    implemented for us with the RedHat Linux operating system where
    it manages every file on the whole system. In OpenPKG RPM is used
    only for managing all files in a particular filesystem hierarchy
    dedicated to the installation of third-party software packages
    provided by the OpenPKG project.

    Internally the OpenPKG bootstrap package is based on the
    following particular vendor products:
        RedHat RPM %{V_rpm}, ZLib %{V_zlib}, GNU Bzip2 %{V_bzip2},
        GNU Gzip %{V_gzip}, GNU Tar %{V_tar}, GNU Patch %{V_patch},
        GNU Make %{V_make}, GNU Bash %{V_bash}, cURL %{V_curl},
        OSSP uuid %{V_uuid}, BeeCrypt %{V_beecrypt}
