-%% This is the EDoc callback module for creating DocBuilder erlref

-%% document based on "overview.edoc".
-%%
-%% Usage examples:
-%%   docb_gen File
-%%   docb_gen -chapter overview.edoc
-%% or (from an Erlang shell)
-%% edoc:file(File, [{layout,docb_edoc_xml_cb},{file_suffix,".xml"},
-%%                  {preprocess,true}]).

-%% The origin of this file is the edoc module otpsgml_layout.erl
