00015  * Configuration options
00016  *
00017  * This file contains macros that pull various objects into the link
00018  * based on definitions in configuration header files. Ideally it
00019  * should be the only place in gPXE where one might need to use #ifdef
00020  * for compile-time options.
00021  *
00022  * In the fairly common case where an object should only be considered
00023  * for inclusion if the subsystem it depends on is present, its
00024  * configuration macros should be placed in a file named
00025  * <tt>config_<i>subsystem</i>.c</tt>, where @e subsystem is the
00026  * object basename of the main source file for that subsystem. The
00027  * build system will pull in that file if @c subsystem.c is included
00028  * in the final gPXE executable built.
