# $EXTRA is a unique identifier consisting of a build version number
# and the abbreviation for the distro. ex. 1rh9, 1centos4, 2wbel3.
# This script uses $EXTRA to customize the RPM spec file,so it must contain
# a string for one of the tested distro: "rh9", "centos4", or "wbel3"
EXTRA=1rh9

# $BUILDROOT is the top directory for the RPM build area. As root, the default
# $BUILDROOT is /usr/src/redhat, but non-root users do not have the permissions
# to build there. Therefore they must create their own build area and set
# $BUILDROOT to point to it. Additionally, they need to change ~/.rpmmacros
# so the rpmbuild tool knows to use $BUILDROOT. To do this, add the following
# line to ~/.rpmmacros:
# %_topdir /home/test/mybuildroot
#
# For more information, see:
# http://genetikayos.com/code/repos/rpm-tutorial/trunk/rpm-tutorial.html
BUILDROOT=/home/test/mybuildroot

# $ARCH can be i386, i686, athlon, etc...

%description
While Wine is usually thought of as a Windows(TM) emulator, the Wine
developers would prefer that users thought of Wine as a Windows
compatibility layer for UNIX. This package includes a program loader,
which allows unmodified Windows 3.1/95/NT binaries to run under Intel
Unixes. Wine does not require MS Windows, but it can use native system
.dll files if they are available.

%package devel
ExclusiveArch: i386
Summary: Wine development environment.
Group: System Environment/Libraries
Requires: wine = %{version}

%description devel
Header, include files and library definition files for developing applications
with the Wine Windows(TM) emulation libraries.
