    longDescription = ''
      Lovely is a lua injector which embeds code into a LÖVE 2d game at runtime.
      Unlike executable patchers, mods can be installed, updated, and removed over and over again without requiring a partial or total game reinstallation.
      This is accomplished through in-process lua API detouring and an easy to use (and distribute) patch system.
