 275 # Author: Przemyslaw Iskra <sparky@pld-linux.org>
 276 #
 277 # Usage:
 278 #       %install_kernel_modules -m <modules> -d <directory>
 279 #
 280 # Options:
 281 #  -m <modules> (required) -- comma-separated list of modules to install,
 282 #               without .ko extension, may be placed in subdirectory
 283 #  -d <directory> (required) -- in what subdirectory modules should be
 284 #               installed (eg. misc, kernel/drivers/net)
 285 #  -s <suffix> -- suffix to use when installing modules, useful when module
 286 #               with same name exists in kernel already
 287 #  -n <file> -- name of modprobe config file to use (without .conf extension)
 288 #               for defining aliases, only useful with -s
 289 #  -D <directory> -- DESTDIR, base directory for installed files,
 290 #               defaults to RPM_BUILD_ROOT
