+#define modprobe_notes_usage \
+"modprobe can (un)load a stack of modules, passing each module options (when\n" \
+"loading). modprobe uses a configuration file to determine what option(s) to\n" \
+"pass each module it loads.\n" \
+"\n" \
+"The configuration file is searched (in order) amongst:\n" \
+"\n" \
+" /etc/modprobe.conf (2.6 only)\n" \
+" /etc/modules.conf\n" \
+" /etc/conf.modules (deprecated)\n" \
+"\n" \
+"They all have the same syntax (see below). If none is present, it is\n" \
+"_not_ an error; each loaded module is then expected to load without\n" \
+"options. Once a file is found, the others are tested for.\n" \
+"\n" \
+"/etc/modules.conf entry format:\n" \
+"\n" \
+" alias <alias_name> <mod_name>\n" \
+" Makes it possible to modprobe alias_name, when there is no such module.\n" \
+" It makes sense if your mod_name is long, or you want a more reprenstative\n" \
+" name for that module (eg. 'scsi' in place of 'aha7xxx').\n" \
+" This makes it also possible to use a different set of options (below) for\n" \
+" the module and the alias.\n" \
+" A module can be aliased more than once.\n" \
+"\n" \
+" options <mod_name|alias_name> <symbol=value ...>\n" \
+" When loading module mod_name (or the module aliased by alias_name), pass\n" \
+" the \"symbol=value\" pairs as option to that module.\n" \
+"\n" \
+"Sample /etc/modules.conf file:\n" \
+"\n" \
+" options tulip irq=3\n" \
+" alias tulip tulip2\n" \
+" options tulip2 irq=4 io=0x308\n" \
+"\n" \
+"Other functionality offered by 'classic' modprobe is not available in\n" \
+"this implementation.\n" \
+"\n" \
+"If module options are present both in the config file, and on the command line,\n" \
+"then the options from the command line will be passed to the module _after_\n" \
+"the options from the config file. That way, you can have defaults in the config\n" \
+"file, and override them for a specific usage from the command line.\n"
