+=head1 NAME
+
+FS::UI::Base - Base class for all user-interface objects
+
+=head1 SYNOPSIS
+
+  use FS::UI::SomeInterface;
+  use FS::UI::some_table;
+
+  $interface = new FS::UI::some_table;
+
+  $error = $interface->browse;
+  $error = $interface->search;
+  $error = $interface->view;
+  $error = $interface->edit;
+  $error = $interface->process;
+
+=head1 DESCRIPTION
+
+An FS::UI::Base object represents a user interface object.  FS::UI::Base
+is intended as a base class for table-specfic classes to inherit from, i.e.
+FS::UI::cust_main.  The simplest case, which will provide a default UI for your
+new table, is as follows:
+
+  package FS::UI::table_name;
+  use vars qw ( @ISA );
+  use FS::UI::Base;
+  @ISA = qw( FS::UI::Base );
+  sub db_table { 'table_name'; }
+
+Currently available interfaces are:
+  FS::UI::Gtk, an X-Windows UI implemented using the Gtk+ toolkit
+  FS::UI::CGI, a web interface implemented using CGI.pm, etc.

+=head1 BUGS
+
+This documentation is incomplete.
+
+There should be some sort of per-(freeside)-user preferences and the ability
+for specific FS::UI:: modules to put their own values there as well.
