/*
 * @progname       ll2html.ll
 * @version        2005-11-19
 * @author         JRE Jim Eggert
 * @category       
 * @output         HTML
 * @description
 *
 *  This report program converts a LifeLines database into html documents.
 *  Family group records are created for each selected individual in
 *  the database.  These records are written in files containing clumps
 *  of individuals of a user-selected size.  Index files are generated
 *  for an index document.  Or, optionally, all output is sent to
 *  one file.
 *
 *  You will need to change the contents of proc html_address() and to
 *  set the value of HREF appropriately to your server.
 *  You need to set the value of PATH to point to the directory to put
 *  the files into. If you have 1000 individuals in your database this
 *  program will create up to 1027 files, one for each individual and
 *  up to 27 index files, if you set the clump size to one.
 *
 *  This program will also generate three pedigree charts for the root
 *  individual and descendants charts for selected individuals.
 *
 *  You also need to set the value of HOST to be the http server and
 *  path where you will server these files from.
 *
 *  History
 *   01-07-94  sew; Created.
 *   11-18-94  jre; Added clump capability.
 *   02-16-95  jre; Added privacy option.
 *   03-06-95  jre; Added pedigree table, better sorting.
 *   05-10-95  jre; Added descendants charts.
 *   05-02-97  jre; Added ISO8859 encoding in GENDEX.txt file.
 *   07-09-99  jre; Added background decorations, improved HTML.
 *   01-15-00  jre; Fixed quicksort bug
 *   11-19-05  jre; Updated released version to rev 12.  Many changes.
