"""
Example providing a clean context for when top==out.

When top==out, waf will not do anything by default
in the clean or distclean operations, because it is dangerous.
The example below illustrates project-specific cleaning operations.

Notes:

- The clean operation below can only remove the generated file that
  are created during the current build (intermediate .o files)
  will not be removed

- File outputs of dynamic builds cannot be removed
  (output files are to be known in advance)

- The distclean operation, which normally removes the build folder
  completely plus some files, is also modified to remove
  the rest of waf-generated files.
