Fedora 19 changed how Ruby requirements are specified. This is a dummy package to ease the transition of Fedora 18 => Fedora 19 third-party packages.

# Dummy ruby-abi spec file for Fedora 19.
#
# In Fedora 19, the packaging team decided to change the long-standing RPM spec file requirement statement from
#
#
#     Requires: ruby(abi)
#
# to
#
#     Requires: ruby(release)
#
#
# All of the RPM spec files for packages provided by Fedora have been updated accordingly. 
# However, at this writing many third-party repositories only have packages available for Fedora 18,
# which means they are using ruby(abi).
#
# In order to avoid rebuilding lots of Fedora 18 packages that are otherwise compatible with Fedora 19,
# I have created a RPM that just satisfies this ruby(abi) requirement.
#
# This solves errors like
#
# Error: Package: puppet-3.2.2-1.fc18.noarch (puppetlabs-products)
#            Requires: ruby(abi) >= 1.8
#
#
# Error: Package: 1:foreman-installer-1.2.0-1.fc18.noarch (foreman)
#            Requires: ruby(abi)
#
# ============================
#
# Build instructions:
#
# yum install rpmdevtools
#
# rpmdev-setuptree
#
# Download ruby-abi.spec to ~/rpmdev/SPECS/
#
# rpmbuild -ba ~/rpmdev/SPECS/ruby-abi.spec
#
# # Install the package
# rpm -iv ~/rpmdev/RPMS/noarch/ruby-abi-2.0.0-1.fc19.noarch.rpm

%description

Fedora 19 switched from using ruby(abi) for RPM requirements to
ruby(release). Some third-party packages still use the old
requirement and refuse to install. This package only
satisfies that requirement in name only and does not install
any files.
