A configuration file can instruct SCons to read up subsidiary configuration files. Subsidiary files are specified explicitly in a configuration file via the SConscript method. As usual, multiple file names may be specified with white space separation, or in an array:

	SConscript('other_file')
	SConscript('file1 file2')
	SConscript(['file3', 'file4'])
	SConscript(['file name with white space'])
	

An explicit sconscript keyword may be used:

	SConscript(sconscript = 'other_file')
	

Including subsidiary configuration files is recursive: a configuration file included via SConscript may in turn SConscript other configuration files.
