    longDescription = ''
      LDMud started as a project to clean up and modernize Amylaar's LPMud
      gamedriver. Primary goals are full documentation, a commented source body
      and out-of-the-box support for the major mudlibs, of which the commented
      source body has been pretty much completed. During the course of work
      a lot of bug fixes and improvements found their way into the driver - much
      more than originally expected, and definitely enough to make LDMud
      a driver in its own right.
