+"""engine.SCons.Variables.ListVariable
+
+This file defines the option type for SCons implementing 'lists'.
+
+A 'list' option may either be 'all', 'none' or a list of names
+separated by comma. After the option has been processed, the option
+value holds either the named list elements, all list elemens or no
+list elements at all.
+
+Usage example:
+
+ list_of_libs = Split('x11 gl qt ical')
+
+ opts = Variables()
+ opts.Add(ListVariable('shared',
+ 'libraries to build as shared libraries',
+ 'all',
+ elems = list_of_libs))
+ ...
+ for lib in list_of_libs:
+ if lib in env['shared']:
+ env.SharedObject(...)
+ else:
+ env.Object(...)
