+Reads a specified configuration file, then writes a new configuration file.
+This can be used to initialize the configuration from e.g. an arch-specific
+configuration file. This input configuration file would usually be a minimal
+configuration file, as generated by e.g. savedefconfig.
+
+The default output filename is '.config'. A different filename can be passed in
+the KCONFIG_CONFIG environment variable.
