Dragon Flame is a freeware application based on Hiswelókë's Sindarin dictionary, developed by Didier Willis and Benjamin Babut. It was first released in December 2002. The latest version, Dragon Flame 2.0 for Windows, was from December 2003, and Dragon Flame 2.0.1 for Linux from July 2004.
Thomas Deniau contributed a complete rewrite for Mac OS systems in 2004, under the name Hesperides.
Both software were distributed with their source code, under the terms of the GNU General Public License.
It should be noted that much material has been published since then. Dragon Flame and Hesperides both embed fairly old versions of the Sindarin lexicon (respectively v0.993 from 2003 and v0.994 from 2004) and were not updated. The authors have no plans of releasing new versions of these programs and do not recommend relying on them for any serious work.
