%description
This is a virtual RPM package. It contains no actual files. It uses the
\`Provides' token from RPM 3.x and later to list many of the shared libraries
and interpreters that are part of the base operating system and associated
subsets for $osname.
This virtual package was constructed based on the vendor/system software
installed on the $osname machine named $hostname, as of the date
$date. It is intended to supply dependency
information about the OS package: $pkg, version: $pkg_version,
