%description
Python is an interpreted, object-oriented programming language, and is
often compared to Tcl, Perl, Scheme, or Java.

This package is installed in /opt/python in such a way that multiple
Python version may live there next to each other.

%description -n opt-python-libpython3
Python is an interpreted, object-oriented programming language, and is
often compared to Tcl, Perl, Scheme, or Java.

This package contains a single symbol link to resolve a conflict
between libpython3 versions.  (See http://bugs.python.org/issue17975)
