"""
|
|
Add a pre-build hook to remove all build files
|
|
which do not have a corresponding target
|
|
|
|
This can be used for example to remove the targets
|
|
that have changed name without performing
|
|
a full 'waf clean'
|
|
|
|
Of course, it will only work if there are no dynamically generated
|
|
nodes/tasks, in which case the method will have to be modified
|
|
to exclude some folders for example.
