## Installed Constants

When you install this application, a number of files containing various constants are created based on the answers to the questions the install script asked.

Most constants are stored in the PHP file Config/Constants.inc. This provides constant values for directories, user names etc. both for the web application and for all of the Perl scripts.

There are some other files created, some of which have to be protected from casual viewing because they contain the MySQL password of the QuartzPVR database. The full pathname of the files, as installed on this system are:
