.xml files, in the xmldoc/ 
subdirectory. These are the master copies that no user ever should 
touch, but that are used to generate the variants below..html files, in the htmldoc/ 
subdirectory. You can open your own locally installed copy of the 
Welcome.html file in your web browser and thereafter 
navigate among all the pages. You can learn which parameters are free 
to be changed, but not change anything, except by brute-force 
cut-and-paste to a file of your own..php files, in the phpdoc/ 
subdirectory. For these files to provide the functionality described 
above they have to accessed via a webserver. The one where you have 
your homepage should work fine. Alternatively you can use pages already 
available on another server.phpdoc/ subdirectory there. In addition to the 
.php code this includes a few more files, plus a 
subdirectory named files where the temporary files 
are stored. This subdirectory must have public write access to work 
(chmod a+w files if not).files actually remain 
unless the RESET button is used. The good news is that this makes 
it possible to recover a file that otherwise might be lost. The bad 
news is that the files directory may need to be cleaned 
up from time to time. (But typically the files are pretty small, so 
this should not be a major problem.)name-of-flag/mode/parameter/word = valuewith one variable per line. Thereafter all the settings on the page are restored to their default values.
