-<p>The LGRx bundle provides packages and definitions for typesetting

-support for Unicode input and macros for Greek letters in
-non-Greek text.</p>
+<p>The LGR font encoding is the de-facto standard for Greek
+typesetting with (8-bit) LaTeX. However, the encoding definition
+file that ships with <a class="reference external" href="http://mirror.ctan.org/help/Catalogue/entries/babel.html">babel</a> misses many of the definitions common
+since the advent of the NFSS <a class="citation-reference" href="#fntguide" id="id1">[fntguide]</a>.</p>
+<p>The <cite>lgrx</cite> bundle provides packages and definitions for
+typesetting Greek text with fonts in the LGR encoding. It works
+for both, monotonic and polytonic Greek, independent of the
+<cite>babel</cite> package.</p>
+<p>The bundle is available from <a class="reference external" href="http://www.ctan.org/tex-archive/macros/latex/contrib/lgrx">CTAN</a> and included in TeXLive
+2012. Development takes place at the <a class="reference external" href="http://milde.users.sourceforge.net/LGR/">Sourceforge</a>.</p>
