As astronomical software development expands from historical data reduction
platforms towards more sophisticated Python applications,
non-technically-focused users can struggle with installing and maintaining
a large number of heterogeneous dependencies. PyRAF has successfully
bridged the gap between IRAF and Python, but managing dependencies falls
outside its scope. A few existing Python distributions make installation
easy, but don't cater for specific needs (such as dependence on IRAF). STScI
and Gemini have therefore developed a prototype, easy-to-install software
distribution for Linux and OSX known provisionally as the 'Unified Release'
(UR).

Currently the UR includes STScI Python and its dependencies (eg. Python,
NumPy, IRAF 2.15), as well as Matplotlib & Tk, SciPy, a number of IRAF
packages, DS9, X11IRAF and some testing and documentation tools. Its scope
extends to complementary non-Python/IRAF software, but we do not intend to
produce a comprehensive (Scisoft-like) distribution of tools for astronomy,
nor to satisfy every installation preference. Our focus is on providing a
simple way to run key tools, for users with minimal support resources and
who may not have administrative privileges. Unlike most comparable
distributions, our approach includes basic provision for in-place software
additions and updates.

Recently we have completed a first internal version of the UR for both
Linux and OSX, which we shall briefly demonstrate. We plan to make our
first public release during the coming months.
