 *  @file TAO.pidl
 *
 *  $Id$
 *
 *  This file contains TAO-specific idl interfaces (not part of CORBA
 *  2.6).
 *
 *  The steps to regenerate the code are as follows:
 *
 * 1. Run the tao_idl compiler on the pidl file.  The command used for
 *   this is:
 *
 *   tao_idl
 *       -o orig -Gp -Gd -Ge 1 -Gv -DCORBA3
 *       -Wb,export_macro=TAO_Export
 *       -Wb,pre_include="ace/pre.h"
 *       -Wb,post_include="ace/post.h"
 *       -Wb,export_include="tao/corbafwd.h" TAO.pidl
 *
 *   2. Then patch the generated code.  The patch fixes the interface
 *   repository IDs, disables the code under certain configurations,
 *   and eliminates cycles in the include dependencies.
 *
 *   Apply patches using the following commands:
 *
 *   patch < diffs/TAOC.h.diff
 *   patch < diffs/TAOC.i.diff
 *   patch < diffs/TAOC.cpp.diff
 *
 *   @note The diffs were generated with these commands:
 *
 *   diff -wBbu orig/TAOC.h TAOC.h > diffs/TAOC.h.diff
 *   diff -wBbu orig/TAOC.i TAOC.i > diffs/TAOC.i.diff
 *   diff -wBbu orig/TAOC.cpp TAOC.cpp > diffs/TAOC.cpp.diff
