<h2 id="history">History</h2> <p>groff is an original implementation written primarily in <a href="/facts/C%252B%252B/Et0F2qn9">C++</a> by <a href="/facts/James_Clark_(programmer)/SXyEkoMz">James Clark</a> and is modeled after <a href="/facts/Ditroff/NtPk6T03">ditroff</a>, including many extensions. The first version, 0.3.1, was released June 1990. The first stable version, 1.04, was announced in November 1991. groff was developed as <a href="/facts/Free_software/IaoVtJXn">free software</a> to provide an easily obtained replacement for the standard AT&T troff/nroff package, which at the time was proprietary, and was not always available even on branded <a href="/facts/UNIX/0pNL2seI">UNIX</a> systems. In 1999, Werner Lemberg and Ted Harding took over maintenance of groff.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> </p> <h2 id="see-also">See also</h2> <ul> <li>Free and open-source software portal</li></ul> <ul><li><a href="/facts/TeX/HDrl3Yvd">TeX</a></li> <li><a href="/facts/Desktop_publishing/gUPtzSnH">Desktop publishing</a></li></ul> <h2 id="notes">Notes</h2> <h2 id="external-links">External links</h2> <ul><li><a href="https://www.gnu.org/software/groff/">Official website</a> </li> <li><a href="https://lists.gnu.org/archive/html/groff/">groff mailing list archive</a> (searchable)</li> <li><a href="https://web.archive.org/web/20070930015427/http://www.nabble.com/Groff---General-f1673.html">Groff Forum</a>, hosted by <a href="http://www.nabble.com">Nabble</a>, archiving the groff mailing list into a searchable forum (sadly none of the emails are visible today).</li> <li><a href="http://troff.org">troff.org</a> gives background and examples of troff, including the GNU roff implementation.</li> <li><a href="http://www.schaffter.ca/mom/mom-01.html">Home page of mom macros</a></li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>Laha, Manas (17 June 2003).
