This program allows the user to select a group of individuals from a database
and generate a set of HTML files for them. It allows writing multiple people 
per HTML file, and will create an index file and a GENWEB.txt file for genweb
indexing of the resulting data.

Before running this program, you will want to customize some global values
for your site. In the original release, they are set as follow:

  set(db_owner, getproperty("user.fullname"))
  set(owner_addr, getproperty("user.email"))
  set(use_image, 1)               
  set(genweb_image, "../../pics/genweb.gif")
  set(use_page, 1)                
  set(genweb_page, "../genweb.html")
  set(page_name, "genweb page")   
  set(html_index, 0)

The first two sets will get your fullname and email address from the 
corresponding user properties.  They do not require editing this file.
The other customizations require editing of this file.
It also says to put an image at the top of each HTML file and specifies
that the image is called genweb.gif. Next, it specifies that a link to my
base page be added to each HTML file, that the location of the base page is
genweb.html, and that the text for the link be "genweb page". It also says
not to use and <ISINDEX> tag in the INDEX.html file.

The program, when run, will request a person to start with. It then allows 
selection of additional people by following family links. It then allows 
addition of all ancestors of the selected set or of the first individual, 
and then all descendants of the selected set or of the orignal individual. 
It also allows addition of all persons with a specified number of relations 
to any individual in any of the groups added above.

For each person asked about, you will be given some information on them to
aid in deciding if they are the one you want or not. This is similar to a
person display when browsing with LifeLines. 

Note: This program will assume that you have a directory called genweb in your
output directory (as specified by LL_REPORTS) and will write all output files
in that directory. If the genweb directory does NOT exist (at least, with
LL302) you will be prompted for the name of each output file. Be aware that
if you use this to name the files diffently, the references within the files
will NOT be changed to reflect the new file name!

Future Enhancements (Let me know if you want to do one of these for me!):
  A hierarchical index would be a nice option.
  Need to add descendant and ancestor (pedigree) charts.
  Add seperate page(s) for sources and generate hyperlinks to them.

Thanks to Tom Wetmore for many small routines that have been addapted for
use in this program as well as LifeLines itself.
