+    longDescription = ''
+      OpenOMF is an open-source remake of the 1994 DOS fighting game One Must
+      Fall 2097 by Diversions Entertainment. It reimplements the original
+      engine from scratch, uses the original (now freeware) game assets, and
+      adds modern conveniences such as online netplay.
+
+      Includes remixed music mod. To add other mods: drop its .zip file
+      into the user mods directory as-is; it does not need to be extracted.
+
+      The user mods directory is <state>/mods, where <state> is resolved at
+      launch in the following order.
+
+        1. $OPENOMF_STATE_PATH, if set
+        2. $XDG_STATE_HOME, if set
+           (e.g. ~/.local/state, giving ~/.local/state/mods)
+        3. SDL's preference path, ~/.local/share/OpenOMF/mods
+    '';
