+/*!
+
+  \brief GConfItem is a simple C++ wrapper for GConf.
+
+  Creating a GConfItem instance gives you access to a single GConf
+  key.  You can get and set its value, and connect to its
+  valueChanged() signal to be notified about changes.
+
+  The value of a GConf key is returned to you as a QVariant, and you
+  pass in a QVariant when setting the value.  GConfItem converts
+  between a QVariant and GConf values as needed, and according to the
+  following rules:
+
+  - A QVariant of type QVariant::Invalid denotes an unset GConf key.
+
+  - QVariant::Int, QVariant::Double, QVariant::Bool are converted to
+    and from the obvious equivalents.
+
+  - QVariant::String is converted to/from a GConf string and always
+    uses the UTF-8 encoding.  No other encoding is supported.
+
+  - QVariant::StringList is converted to a list of UTF-8 strings.
+
+  - QVariant::List (which denotes a QList<QVariant>) is converted
+    to/from a GConf list.  All elements of such a list must have the
+    same type, and that type must be one of QVariant::Int,
+    QVariant::Double, QVariant::Bool, or QVariant::String.  (A list of
+    strings is returned as a QVariant::StringList, however, when you
+    get it back.)
+
+  - Any other QVariant or GConf value is essentially ignored.
+
+  \warning GConfItem is as thread-safe as GConf.
