/**
|

* PreferencesFactory implementation that stores the preferences in a user-defined file. To use it, set the system
|
|
* property <tt>java.util.prefs.PreferencesFactory</tt> to <tt>net.sourceforge.tuned.pref.FilePreferencesFactory</tt>
|
|
* <p/>
|
|
* The file defaults to [user.home]/.fileprefs, but may be overridden with the system property
|
|
* <tt>net.sourceforge.tuned.pref.FilePreferencesFactory.file</tt>. Modified by cstamas, switched to SLF4J logging, and
|
|
* exposed preferences file property.
