+ * UAT maintains a dynamically allocated table accessible to the user
+ * via a file and/or via GUI preference dialogs.
+ *
+ * The file is read from and written in the personal configuration directory. If
+ * there is no such file, defaults will be loaded from the global data
+ * directory.
+ *
+ * The behaviour of the table is controlled by a series of callbacks which
+ * the caller (e.g. a dissector) must provide.
+ *
+ * BEWARE that the user can change an UAT at (almost) any time (via the GUI).
+ * That is, pointers to records in an UAT are valid only during the call
+ * to the function that obtains them (do not store pointers to these records).
+ * The records contents are only guaranteed to be valid in the post_update_cb
+ * function. (Implementation detail: currently a race condition is possible
+ * where the UAT consumer (dissector code) tries to use the UAT while the GUI
+ * user frees a record resulting in use-after-free. This is not ideal and might
+ * be fixed later.)
+ *
+ * UATs are meant for short tables of user data (passwords and such), there is
+ * no quick access, you must iterate through them each time to fetch the record
+ * you are looking for.
+ *
+ * Only users via GUI or editing the file can add/remove records, your
+ * (dissector) code cannot.
