85# conf:	  Used for defconfig, oldconfig and related targets
86# mconf:  Used for the mconfig target.
87#         Utilizes the lxdialog package
88# qconf:  Used for the xconfig target
89#         Based on QT which needs to be installed to compile it
90# gconf:  Used for the gconfig target
91#         Based on GTK which needs to be installed to compile it
