  Goes through your asset set directory.  (See below for how to specify
  it, and what the default is.)  Finds all .j2k images, .txt files, and
  .lsl files in that directory and all subdirectories.  Generates an
  Asset Set XML file for all of those files.  Also generates library
  Inventory Folder and Inventory Item XML files for all of those assets,
  organized in a folder hierarchy that matches the directory hierarchy.

  Additional assets that already exist in the grid's asset store may be
  specified in each directory in a file named "addassets.lis".

  For more documentation, see http://opensimulator.org/wiki/Custom_Libraries

  When done, you will need to manually add your asset directory to the
  OpenSim AssetSets.xml file (in "assets" under the OpenSim bin
  directory), and your inventory XML files to the Libraries.xml file (in
  "inventory" under the OpenSim bin directory).
