In ruby193 SCL, there is available %{_root_bindir}/%{scl_prefix}ruby, i.e. ruby193-ruby to provide easy way how to execute ruby from SCL, without need of calling "scl enable ruby193 'ruby'". It is created by following snippet:



# Create the %%{_root_bindir} wrapper:
%if 0%{?scl:1}
mkdir -p %{buildroot}%{_root_bindir}
cat > %{buildroot}%{_root_bindir}/%{scl_prefix}ruby << 'EOF'
#!/bin/bash

COMMAND="ruby $@"
scl enable %{scl} "$COMMAND"
EOF
chmod a+x %{buildroot}%{_root_bindir}/%{scl_prefix}ruby
%endif



Since this very useful concept and is requested to be added also for other packages, it would be nice, if there is available some rpm macro, such as %scl_bin_wrapper, which would create the wrapper for us.
