 290 #
 291 # Usage:

 293 #
 294 # Options:
 295 #  -m <modules> (required) -- comma-separated list of modules to install,
 296 #               without .ko extension, may be placed in subdirectory
 297 #  -d <directory> (required) -- in what subdirectory modules should be
 298 #               installed (eg. misc, kernel/drivers/net)
 299 #  -s <suffix> -- suffix to use when installing modules, useful when module
 300 #               with same name exists in kernel already
 301 #  -n <file> -- name of modprobe config file to use (without .conf extension)
 302 #               for defining aliases, only useful with -s
 303 #  -D <directory> -- DESTDIR, base directory for installed files,
 304 #               defaults to RPM_BUILD_ROOT
