// Implementation notes on preferences:
//
// Preferences are edited and stored on BOINC servers.
// The native representation of preferences is XML.
// The client maintains the preferences (in XML form)
// and mod time in the state file and in memory.
// It includes these items in each scheduler request message.
// A scheduler reply message may contain a more recent set of preferences.
//
// Some preference items are used by the core client.
// The XML is parsed into a structure containing these items.
//
// Preferences may include project-specific elements.
// When an application is run, the core client checks for project-specific
// preferences and puts them in a file "prefs.xml" in the slot directory.

// The following structure is a parsed version of the prefs file
//
