+ |
+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(...) |
