# The original package name
# e.g. qemu
#
%define oldname libgcc

#
# The architectures this meta package is built on
# e.g. i586
#
%define myexclusive i586 x86_64

#
# The required package for building this package
# This can be distribution dependent. Good start is:
# e.g. rpm grep tar sed patchelf
#
BuildRequires: rpm grep tar sed patchelf

#
# Additional required packages needed in addition to those of original package
# e.g. (usually empty) for an accelerator to be 100% compatible
#
#Requires:      <usuallyemptlylist>
