  32  // it is an install, otherwise it is an upgrade, however nothing is ever that
  33  // simple.  The possibilities are:
  34  // 1. A simple install as describe above, no config.php, no database
  35  // 2. Someone has read that it needs a writable config.php so creates an empty one
  36  // 3. Someone has uploaded the dotproject.sql file and then run the installer
  37  // 4. Combination of 2 and 3
  38  // 5. It is an upgrade - there must be a config.php and a database.
