"""Variable type for list Variables.
|
|
|
|
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 elements or no
|
|
list elements at all.
|
|
|
|
Usage example::
|
|
|
|
list_of_libs = Split('x11 gl qt ical')
|
|
|
|
opts = Variables()
|
|
opts.Add(
|
|
ListVariable(
|
|
'shared',
|
|
help='libraries to build as shared libraries',
|
|
default='all',
|
|
elems=list_of_libs,
|
|
)
|
|
)
|
|
...
|

|
