65# Shared Makefile for the various kconfig executables:
66# conf:	  Used for defconfig, oldconfig and related targets
67# mconf:  Used for the mconfig target.
68#         Utilizes the lxdialog package
69# qconf:  Used for the xconfig target
70#         Based on QT which needs to be installed to compile it
71# gconf:  Used for the gconfig target
72#         Based on GTK which needs to be installed to compile it
73# object files used by all kconfig flavours
