The way preferences are implemented in cvsgui is via subclasses of 
CPersistent. There are a couple of subclasses for various data types 
(integer values, boolean values, string values, string lists, etc.). 
Usually, one can just use one of the existing subclasses and 
instantiate a static/global variable, which will do all the magic for 
you, e.g.:

static CPersistentInt gKserverPort("P_KserverPort", -1, kAddSettings);

or

static CPersistentBool gQuietOption("P_QuietOption", false);


You can use the persitent value objects just like their underlying data 
type (since they provide conversion operators), e.g.

if ( gQuietOption ) {
	// do something quiet
}

common/CvsPrefs.cpp instantiates the globally known preferences, but 
you can just put the persistent objects as static instances in any 
place you want.
If you specify the 'kAddSettings' parameter, the prefs are per-sandbox, 
otherwise, they're app-global.
